Xenotransplantation. (1/119)

As transplantation waiting lists lengthen because of the shortage of donor organs, the death rates of patients continue to rise. Xenotransplantation offers the potential to solve the problem of organ shortage br providing an unlimited supply of healthy donor organs. However, there are several barriers to xenotransplantation, including graft rejection, potential xenozoonosis, physiologic incompatibilities and ethical concerns. Experimental xenotransplantation studies continue in several areas, ranging from tissue to whole- organ grafting. Clinical studies continue in the area of tissue xenotransplantation. Trials with extracorporeal xenografts in an acute setting to support fulminant organ failure are likely to begin in the near future. The reintroduction of whole-organ xenotransplantation must be based on sound scientific analysis with broad societal input so as to offer the maximal benefit to transplant recipients and their families.  (+info)

Long-term results of artificial anal sphincter implantation for severe anal incontinence. (2/119)

OBJECTIVE: To evaluate the long-term results of implantation of an artificial anal sphincter (AAS) for severe anal incontinence. SUMMARY BACKGROUND DATA: Implantation of an AAS is one of the options for treatment of anal incontinence when standard operations have failed. It is the only surgical option for treatment of anal incontinence in patients with neurologic disease that affects the pelvic floor and the muscles of the lower limb. METHODS: Seventeen patients underwent implantation of an AAS before 1993. These patients have been followed and their continence status evaluated. RESULTS: Two patients died of unrelated causes within the first 3 years after surgery, and in three patients the AAS was explanted because of infection. During the follow-up period, four patients had the AAS removed because of malfunction, and eight patients had a functioning AAS > or =5 years after the primary implantation. Five of these patients had revisional procedures, mainly because of technical problems in the early part of the study, when a urinary sphincter or slightly modified urinary sphincter was used. Continence at follow-up was good in four patients and acceptable in three, whereas one patient still had occasional leakage of solid stool. One patient had rectal emptying problems, which she managed by enema. CONCLUSIONS: An AAS based on the same principles as the artificial urinary sphincter seems to be a valid alternative in selected patients when standard surgical procedures have failed or are unsuitable. Approximately half of the patients have an adequate long-term result. Infectious complications still present a problem, whereas mechanical problems are less frequent with the modification of the device now available.  (+info)

A cell-based constitutive relation for bio-artificial tissues. (3/119)

By using a combination of continuum and statistical mechanics we derive an integral constitutive relation for bio-artificial tissue models consisting of a monodisperse population of cells in a uniform collagenous matrix. This constitutive relation quantitatively models the dependence of tissue stress on deformation history, and makes explicit the separate contribution of cells and matrix to the mechanical behavior of the composite tissue. Thus microscopic cell mechanical properties can be deduced via this theory from measurements of macroscopic tissue properties. A central feature of the constitutive relation is the appearance of "anisotropy tensors" that embody the effects of cell orientation on tissue mechanics. The theory assumes that the tissues are stable over the observation time, and does not in its present form allow for cell migration, reorientation, or internal remodeling. We have compared the predictions of the theory to uniaxial relaxation tests on fibroblast-populated collagen matrices (FPMs) and find that the experimental results generally support the theory and yield values of fibroblast contractile force and stiffness roughly an order of magnitude smaller than, and viscosity comparable to, the corresponding properties of active skeletal muscle. The method used here to derive the tissue constitutive equation permits more sophisticated cell models to be used in developing more accurate representations of tissue properties.  (+info)

Tissue engineering a blood vessel substitute: the role of biomechanics. (4/119)

The engineering of a functional blood vessel substitute has for a quarter of a century been a "holy grail" within the cardiovascular research community. Such a substitute must exhibit long term patency, and the critical issues in this area in many ways are influenced by biomechanics. One of the requirements is that it must be non-thrombogenic, which requires an "endothelial-like" inner lining. It also must have mechanical strength, i.e. a burst pressure, sufficient to operate at arterial pressures. Ideally, however, it must be more than this. It also must have viscoelastic properties that match those of the native vessel being replaced. Finally, if it is to be able to adapt to changing blood flow conditions, it must exhibit vasoactivity, a function which in and of itself can be viewed as biomechanical in nature. To achieve this requires having, as part of the construct, vascular smooth muscle cells, which are contractile in nature and oriented in a circumferential direction. Only if an engineered blood vessel substitute possesses all of these functional characteristics, can one say that the functionality exhibited by a native vessel is being mimicked.  (+info)

Artificial cornea: towards a synthetic onlay for correction of refractive error. (6/119)

Synthetic onlays that are implanted onto the surface of the cornea have the potential to become an alternative to spectacles and contact lenses for the correction of refractive error. A successful corneal onlay is dependent on development of a biocompatible polymer material that will maintain a healthy cornea after implantation and that will promote growth of corneal epithelial cells over the onlay, and development of a method for attachment of the onlay with minimal surgical invasiveness. The ideal onlay should be made of a material that is highly permeable yet has sufficient surface characteristics to stimulate stable and firm attachment of the corneal epithelium over the onlay. Recent research indicates that collagen I coated polymer materials that mimic the basement membrane of the corneal epithelium promote the most favorable growth of epithelial cells in vivo in comparison to wholly biological or synthetic materials.  (+info)

Chemical sensor based on nonlinearity: principle and application. (7/119)

Novel chemical sensors based on a time-dependent nonlinear response are reviewed. The strategy is to artificially mimic information transduction in living organisms. In taste and olfaction, information of chemical structure and concentration is transformed into nervous impulses in the nervous cell, i.e., time-dependent multi-dimensional information. Because the excitation and pulse generation in the nervous cell are typically nonlinear phenomena, it may be worthwhile to utilize the nonlinearity as the multi-dimensional information for molecular recognition. The principle of a "nonlinear" sensor is that a sinusoidal modulation is applied to a system, and the output signal is analyzed. The output signal of the sensor is characteristically deformed from the sinusoidal input depending on the chemical structure and concentration of the chemical stimuli. The characteristic nonlinear responses to chemical stimuli are discussed in relation to the kinetics of chemical compounds on the sensor surface. As a practical application, we introduced electrochemical sensors based on the differential capacitance, semiconductor gas sensors under the application of sinusoidal temperature or diffusion change, and a chemical sensor based on the spatio-temporal information. We demonstrated that mutli-dimensional information based on nonlinearity can provide quite useful information for the analysis of chemical species, even in the presence of another analyte or an interference with a single detector.  (+info)

Midkine, a heparin-binding growth factor, promotes growth and glycosaminoglycan synthesis of endothelial cells through its action on smooth muscle cells in an artificial blood vessel model. (8/119)

To study the interactions between smooth muscle cells and endothelial cells in vitro, we developed an artificial blood vessel model, which consisted of collagen gel containing human aortic smooth muscle cells and human umbilical vein endothelial cells grown on the gel. The blood vessel model was utilized to investigate the role of midkine, a heparin-binding growth factor, in the intercellular interactions that are important in angiogenesis. In the blood vessel model, midkine induced stratification of the endothelial cells and increased their proliferation and glycosaminoglycan synthesis. However, midkine had no effect on the smooth muscle cells or endothelial cells when they were cultured separately. Increased proliferation of the endothelial cells was also attained by coculturing them with smooth muscle cells in the presence of midkine or culturing endothelial cells with the conditioned medium of the smooth muscle cells, which had been treated with midkine. These experiments indicate that the target of midkine was smooth muscle cells, which secreted factor(s) acting on the endothelial cells. We identified interleukin-8 as one such factor; the synthesis of interleukin-8 by the smooth muscle cells was increased by exposure to midkine, and anti-interleukin-8 inhibited the midkine action. Furthermore, interleukin-8 caused stratification of the endothelial cells in the blood vessel model. These results provided evidence that midkine is one of the factors involved in epithelial-mesenchymal interactions.  (+info)

Purpose : The cornea efficiently restricts permeability of topically administered drugs into the eye. Currently, permeability of drug candidates is tested across excised animal corneas ex vivo or using in vitro cell culture models. The purpose of this study was to develop an artificial cornea for drug permeability screening in early drug development that more adequately resembles the human cornea. Methods : Several modifications of artificial corneas were prepared using different hydrogel cross-linking and coating techniques. The apparent permeability coefficient (Papp) values of standard reference molecules across artificial corneas were tested using Navicyte vertical diffusion chambers. Permeability characteristics (tightness, dynamic range) of the artificial cornea was assessed, and the Papp values across artificial cornea were correlated with those of ex vivo rabbit corneas and in vitro human corneal epithelial cell (HCE-T) culture model. HCE-T cells were also grown on top of artificial ...
PURPOSE OF REVIEW:. Artificial corneas are being developed to meet a shortage of donor corneas and to address cases in which allografting is contraindicated. A range of artificial corneas has been developed. Here we review several newer designs and especially those inspired by naturally occurring biomaterials found with the human body and elsewhere.. RECENT FINDINGS:. Recent trends in the development of artificial corneas indicate a move towards the use of materials derived from native sources including decellularized corneal tissue and tissue substitutes synthesized by corneal cells in vitro when grown either on their own or in conjunction with novel protein-based scaffolds. Biologically inspired materials are also being considered for implantation on their own with the view to promoting endogenous corneal tissue.. SUMMARY:. More recent attempts at making artificial corneas have taken a more nature-based or nature-inspired approach. Several will in the near future be likely to be available ...
The term "perfusion" is derived from the French verb perfuse meaning to pour over or through. Perfusionists employ artificial blood pumps to propel open-heart surgery patients blood through their body tissue, replacing the function of the heart while the cardiac surgeon operates.. When a patients blood is continuously removed and returned through plastic tubing to allow health care professionals to perform an artificial organ function on the blood, it is called "extra-corporeal circulation (ECC)" - outside the body blood circulation.. Presently there are many "artificial organs" that can be placed in an ECC to substitute for a patients failing organs. The list of artificial organs presently available for clinical use includes artificial hearts (blood pump), artificial lungs (oxygenator), artificial kidneys (hemodialysis), and artificial livers.. Perfusionists are capable of combining sterile tubing and artificial organs to build an ECC to meet the needs of several physician specialists to ...

Human recombinant collagen can be cross-linked with a variety of chemical cross-linking agents. Cross-linking methods can be tuned to confer collagen-based scaffolds with specific physical properties, improved antigenicity and thermal stability without impeding the ability of the material to integrate into the surrounding tissue and to promote regeneration. Here, we describe a method to cross-link human recombinant collagen using a water soluble carbodiimide. Carbodiimides are referred to as zero-length cross-linking agents as they are not incorporated into the final cross-link and thus pose minimal risk with respect to cytotoxicity. The resulting collagen-based scaffold possesses properties comparable to that of the human cornea and is thus suitable for use as a corneal substitute.. ...

Background. Stem cell therapy to improve cardiac function after myocardial infarction is hampered by poor cell retention, while it may also increase the risk of arrhythmias by providing an arrhythmogenic substrate. We previously showed that porcine adipose tissue-derived-stromal cells (pASC) induce conduction slowing through paracrine actions, whereas rat ASC (rASC) and human ASC (hASC) induce conduction slowing by direct coupling. We postulate that biomaterial microspheres mitigate the conduction slowing influence of pASC by interacting with paracrine signaling.. Aim. To investigate the modulation of ASC-loaded recombinant human collagen-based microspheres, on the electrophysiological behavior of neonatal rat ventricular myocytes (NRVM).. Method. Unipolar extracellular electrograms, derived from microelectrode arrays (8x8 electrodes) containing NRVM, co-cultured with ASC or ASC loaded microspheres, were used to determine conduction velocity (CV) and conduction heterogeneity. Conditioned medium ...
Hmmm, the world of printers might seem to be rather boring to some as improvements in this area are hardly worth reporting on - rarely making headlines, so to speak. Well, printing has taken on a new dimension with the introduction of 3D printers, as you get to deliver what your mind has conceived in an actual, 3D object - which previously you had to spend far more money elsewhere to get that done.. Guess where is another use of 3D printer applicable in our everyday lives? Were talking about using a 3D printer to roll out artificial blood vessels, and these blood vessels might soon see action during transplants of lab-created organs.. It has been the major stumbling block until now in tissue engineering, as boffins had been scratching their heads as to how to supply artificial tissue with nutrients that require the use of capillary vessels to arrive. Why not provide artificial tissue with artificial blood vessels? Thats probably the route that a team at the Fraunhofer Institute in Germany ...
A bi-functional epoxy-based cross-linker, 1,4-Butanediol diglycidyl ether (BDDGE), was investigated in the fabrication of collagen based corneal substitutes. Two synthetic strategies were explored in the preparation of the cross-linked collagen scaffolds. The lysine residues of Type 1 porcine collagen were directly cross-linked using l,4-Butanediol diglycidyl ether (BDDGE) under basic conditions at pH 11. Alternatively, under conventional methodology, using both BDDGE and 1-Ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC)/N-hydroxysuccinimide (NHS) as cross-linkers, hydrogels were fabricated under acidic conditions. In this latter strategy, Cu(BF4)2·XH2O was used to catalyze the formation of secondary amine bonds. To date, we have demonstrated that both methods of chemical cross-linking improved the elasticity and tensile strength of the collagen implants. Differential scanning calorimetry and biocompatibility studies indicate comparable, and in some cases, enhanced properties compared to ...

Keratoprosthesis is a surgical procedure where a diseased cornea is replaced with an artificial cornea. Traditionally, keratoprosthesis is recommended after a person has had a failure of one or more donor corneal transplants. More recently, a less invasive, non-penetrating artificial cornea has been developed which can be used in more routine cases of corneal blindness. While conventional cornea transplant uses donor tissue for transplant, an artificial cornea is used in the Keratoprosthesis procedure. The surgery is performed to restore vision in patients suffering from severely damaged cornea due to congenital birth defects, infections, injuries and burns. Keratoprotheses are made of clear plastic with excellent tissue tolerance and optical properties. They vary in design, size and even the implantation techniques may differ across different treatment centers. The procedure is done by ophthalmologists, often on an outpatient basis. The idea of artificial cornea was first proposed in 1789 by ...
Corneal disease is the second most common cause of blindness in the word. It is estimated that 45 million people worldwide are bilaterally blind and 10 million are affected by corneal blindness. Corneal blindness mostly affects the population in the equatorial zone, due to the high exposure to UV light. Corneal grafting presents complications such as rejections and the lack of donor material and resources. Conventional cornea grafting (keratoplasty) is not advised for patients with bilateral corneal blindness or for those who suffer from a range of clinical problems including tear deficiency, chemical burns and uncontrollable intraocular pressure. At present, an artificial cornea, i.e. a keratoprosthesis (KRPO), is the only alternative to keratoplasty (corneal donor transplantation). Cornea implants consist of a clear optic part and a surrounding ring known as the skirt, which needs to integrate with the sclera of the eye. Currently used skirt materials lead to poor tissue integration, a major ...

A proposed solution to this problem is the idea of "Encapsulated Cell Therapy" (Galletti, 1995). It basically works as follows: The cells used can be either human or other animal cells. These cells are genetically altered to produce whatever it is that is needed in the body (insulin, other needed proteins, hormones, etc.). The cells are then protected from the immune system in a very clever "capsule" system made of a polymer material. This polymer has specially designed pores that are large enough to allow the desired excretion of therapeutic substances, but small enough to keep out the bodys immune system. In effect, we have a cybernetic system here, in which an isolated "colony" of foreign cells lives, protected, inside the humans system. This colony feeds off of the humans blood, and excretes its wastes and its specially designed products into the humans circulatory system.. There are other applications for this type of technology such as pain control systems and treatment of otherwise ...

A poly vinyl chloride (PVC) gel actuator shows great potential for use as an artificial muscle because of such positive characteristics as movement in the air, large deformation, and being light in weight. A bending type actuator using PVC gel was studied previously. In order to construct an artificial muscle it is necessary to compose an actuator which has the characteristics of contraction type deformation. In the present paper we propose an electrode arrangement for a contraction type actuator using PVC gel. Also, we investigate the characteristics of the proposed actuator experimentally and show the effectiveness of the actuator as an artificial muscle. The experimental results showed that the contraction strain of the actuator was about 14%, the response rate was 7Hz, and the output stress was 4kPa. In order to apply the artificial muscle as a control element, we build a linear mathematical model of the electronic and mechanical characteristics. Based on the mathematical model, we design a ...
Purpose: To assess integration of a biosynthetic corneal implant in dogs.. Methods: Three normal adult laboratory Beagles underwent ophthalmic examinations, including slit-lamp biomicroscopy, indirect ophthalmoscopy, applanation tonometry, and Cochet-Bonnet aesthesiometry. Biosynthetic corneas fabricated from glutaraldehyde crosslinked collagen and copolymers of collagen and poly (N-isopropylacrylamide-co-acrylic acid-co-acryloxysuccinimide, denoted as TERP) were implanted into dogs by a modified epikeratoplasty technique. Ophthalmic examinations and aesthesiometry were performed daily for 5 days and then weekly thereafter for 16 weeks. Corneal samples underwent histopathological and transmission electron microscopy examination at 16 weeks.. Results: Implants were epithelialized by 7 days.

The invention relates to a blood vessel treating assembly comprising: an artificial blood vessel inner layer such as an artificial tunica-intima or the like for replacing a section of blood vessel inner layer previously removed from a blood vessel and/or for covering a predetermined length of damaged blood vessel inner layer, wherein said artificial blood vessel inner layer is associated with the existing blood vessel in such a way as to substantially stop any loose parts of the blood vessel from obstructing the stream of blood through said blood vessel; and introducing means for introducing the artificial blood vessel inner layer into the blood vessel.
Purpose: : Patients with Boston Keratoprosthesis Type I require the use of a contact lens to help maintain a moist corneal surface and prevent degradation of the corneal skirt. The chronic use of topical antibiotics in these patients may promote the growth of resistant organisms, yet, to our knowledge, the surveillance of the contact lenses in these patients by scanning electron microscopy has not been performed. The purpose of this study is to perform such microscopy in order to detect possible biofilm formation and/or organism growth prior to the clinical presentation of infection. Methods: : Scanning electron microscopy of contact lenses from Boston KPro Type I patients was performed. Both Kontur large diameter lenses and Focus Night and Day (CIBA Vision) lenses were used, with selection based on adequate fit and patient comfort. All patients were maintained on a prophylactic antibiotic regimen including vancomycin. All contact lenses were removed one week to one month after placed, using ...
Artificial muscle is a generic term used for materials or devices that can reversibly contract, expand, or rotate within one component due to an external stimulus (such as voltage, current, pressure or temperature). The three basic actuation responses - contraction, expansion, and rotation - can be combined together within a single component to produce other types of motions (e.g. bending, by contracting one side of the material while expanding the other side). Conventional motors and pneumatic linear or rotary actuators do not qualify as artificial muscles, because there is more than one component involved in the actuation. Due to their high flexibility, versatility and power-to-weight ratio compared with traditional rigid actuators, artificial muscles have the potential to be a highly disruptive emerging technology. Though currently in limited use, the technology may have wide future applications in industry, medicine, robotics and many other fields. While there is no general theory that ...

The patient is brought into the surgical suite and the anesthesiologist along with operating room nurses prep the patient for surgery. Once the patient is put to sleep the surgeon can begin his portion of the surgery. The chest is opened and the patient is connected to the heart lung machine by the surgeon. Once the patient is connected to the heart lung machine the heart and lungs of the patient are stopped. This is done so that the surgeon has a still field to work on. It is during this time the perfusionist along with the heart lung machine takes over the patients circulation and respiration. This is refereed to as extra-corporeal circulation (E.C.C), which is an artificial organ function of the blood. (AACP) The perfusionist must monitor the changing circulatory process along with keeping the surgeon and anesthesiologist updated on the patients condition. After the surgery, the perfusionist must provide support to the patients circulation until everything is regulated at which point the ...

This paper deals with the recent development of two types of non-invasive physiological monitoring systems for possible application in an unconstrained manner to normal subjects for health care as well as to patients and/or outpatients with disorders or with life support systems (artificial organs and organ transplantations). One is an ambulatory monitoring system which allows automatic acquisition of blood pressure, cardiac output and other cardiovascular hemodynamic parameters on a beat-by-beat basis using the volume-compensation and transthoracic electrical admittance method. The other is a home monitoring system installed in a lavatory which can measure body and excreta weight together with the ballistocardiogram as an index of cardiac ejecting function in an unaware fashion without attachment of any sensors to the subject's body and without special operations for measurement during toilet use. Outlines of these two systems and monitoring results of laboratory and field testings are presented,

Scientists at Newcastle University, UK, and the University of California have developed a new method to grow curved human corneas improving the quality and transparency - solely by controlling the behaviour of cells in a dish.. The research publishing today in Advanced Biosystems has revealed that corneal cells isolated from human donors and grown on curved surfaces arrange themselves in a very regular lattice-like organisation.. Cells grown this way achieve the precise alignment that gives the human cornea its strength and transparency. This new technique may revolutionise how artificial tissues are traditionally grown in laboratories around the world.. Lead researcher Che Connon, Professor of Tissue Engineering at Newcastle University explained: "We discovered that the cells grown on a dome-shaped surface behaved differently than those on flat one, crawling over the dome in a lattice-like structure - similar to a pie crust.. "These cells then produced large amounts of aligned collagen, the ...
I have written before on the age of merging electronics and man (Bionics). It would seem that science is forever creeping closer to that elusive dream of growing human parts. Scientist reported in an article in Sci Transl Med 25 August 2010: Vol. 2, Issue 46, p. 46, on the possibility of implanting biosynthetic corneas.. Corneas from human donors are used to replace damaged tissue and treat corneal blindness, but there is a severe worldwide shortage of donor corneas. We conducted a phase 1 clinical study in which biosynthetic mimics of corneal extracellular matrix were implanted to replace the pathologic anterior cornea of 10 patients who had significant vision loss, with the aim of facilitating endogenous tissue regeneration without the use of human donor tissue.. The biosynthetic implants remained stably integrated and avascular for 24 months after surgery, without the need for long-term use of the steroid immunosuppression that is required for traditional allotransplantation. Corneal ...

Can we print bodypart? Yes, now we can do it. Thanks to a new international research. 3D Printed organs come a step closer (GUARDIAN) - For years, scientists have been able to "print" types of human tissue using a 3D printer, but in a significant leap forward by US and Australian researchers they can now make that tissue survive on its own.. Until now a major barrier to them moving from printing tiny sheets of tissue to entire 3D organs is that they hadnt figured out how to develop the blood vessels that provide cells with nutrients and oxygen, and allow them to excrete waste.. This essential process is called "vascularisation" and is necessary if researchers are to ever prevent cells from dying so they can grow large, transplantable organs.. But in a major medical breakthrough, researchers from Sydney and Harvard universities have managed to 3D bio-print capillaries, the tiny channels that allow vascularisation to take place so that cells can sustain themselves and survive.. Using a high-tech ...
As its base material, a team of researchers led by West and BCM molecular physiologist Mary Dickinson chose polyethylene glycol (PEG), a nontoxic plastic thats widely used in medical devices and food. Building on 10 years of research in Wests lab, the scientists modified the PEG to mimic the bodys extracellular matrix - the network of proteins and polysaccharides that make up a substantial portion of most tissues.West, Dickinson, Rice graduate student Jennifer Saik, Rice undergraduate Emily Watkins and Rice-BCM graduate student Daniel Gould combined the modified PEG with two kinds of cells - both of which are needed for blood-vessel formation. Using light that locks the PEG polymer strands into a solid gel, they created soft hydrogels that contained living cells and growth factors. After that, they filmed the hydrogels for 72 hours. By tagging each type of cell with a different colored fluorescent marker, the team was able to watch as the cells gradually formed capillaries throughout the ...
Growing Implants We have sufficiently advanced medicine to the point that artificial body parts are no longer science fiction.

Want to witness the power behind the next generation of artificial muscles for prosthetics and exoskeletons? Look in your fishing tackle box.. According to a recent announcement from researchers at the University of Texas - Dallas, a process that twists and coils fishing line results in an artificial muscle that can lift more than 100 times the weight of a similar-sized human muscle and can be controlled by relatively simple temperature changes. The research has been reported in Discover magazine, Health24, and WebMD, among other outlets. The twisted polymer filament process was developed at the NanoTech Institute at the university. Researchers believe that the technology has immediate applications for exoskeletons but could also be commercialized to create clothing that adapts to changes in temperature. While far less efficient than human muscle, the fibers can generate more than 5 times the energy of an automobile engine.. ...

A little fishing line, a little sewing thread, et voila: muscles! This is Sandra Tsing Loh with the Loh Down on Science, saying:. Well, maybe not so easy as that. Ask Ray Baughman of the University of Texas at Dallas. He and colleagues have teamed up to make artificial muscles from these common materials. Polyethylene and nylon fibers - which are used to make fishing line and sewing thread - are super cheap. Baughmans team twisted and coiled nylon fibers into cords and braids. All twisted up, the cords can store a lot of potential energy. Kind of like a rubberband airplane. Turning and turning the propeller of a toy plane twists the rubberband around the propeller tighter and tighter. Thats stored potential energy. Let it go, and zoom! Rubberband muscle power!. But for nylon muscles, add a little bit of heat and the cords bounce. Thats a lot like our muscle fibers contracting and relaxing with nerve impulses. Only nylon muscles are a hundred times stronger. Artificial muscles could someday ...

Films of conducting polymers can be oxidized and reduced in a reversible way. Any intermediate oxidation state determines an electrochemical equilibrium. Chemical or physical variables acting on the film may modify the equilibrium potential, so that the film acts as a sensor of the variable. The working potential of polypyrrole/DBSA (Dodecylbenzenesulfonic acid) films, oxidized or reduced under constant currents, changes as a function of the working conditions: electrolyte concentration, temperature or mechanical stress. During oxidation, the reactive material is a sensor of the ambient, the consumed electrical energy being the sensing magnitude. Devices based on any of the electrochemical properties of conducting polymers must act simultaneously as sensors of the working conditions. Artificial muscles, as electrochemical actuators constituted by reactive materials, respond to the ambient conditions during actuation. In this way, they can be used as actuators, sensing the surrounding conditions during

Soft robotics has made leaps and bounds over the last decade as researchers around the world have experimented with different materials and designs to allow once rigid, jerky machines to bend and flex in ways that mimic and can interact more naturally with living organisms. However, increased flexibility and dexterity has a trade-off of reduced strength, as softer materials are generally not as strong or resilient as inflexible ones, which limits their use.. Now, researchers at the Wyss Institute at Harvard University and MITs Computer Science and Artificial Intelligence Laboratory (CSAIL) have created origami-inspired artificial muscles that add strength to soft robots, allowing them to lift objects that are up to 1,000 times their own weight using only air or water pressure. The study will be published this week in Proceedings of the National Academy of Sciences (PNAS).. "We were very surprised by how strong the actuators [aka, "muscles"] were. We expected theyd have a higher maximum ...

A low-resistance hydrocarbon-adsorptive cartridge for an air intake of an internal combustion engine comprising a structure for being mounted into a portion of an engine air intake system. The structure is adapted to orient and retain one or more thin sheets of activated carbon sheeting in the intake system. Preferably, a plurality of sheets is oriented such that the leading edge of each sheet is presented to the engine intake air stream, thereby minimizing reduction in total cross-sectional area of the intake system. Preferably, the one or more sheets are spaced apart by a distance that is small relative to the extent of the elements in the direction of engine air flow such that a high probability is created that hydrocarbons migrating out of a shut down engines intake manifold will encounter a surface of at least one of the adsorptive sheets and thus be adsorbed.
