    • New polymeric materials and their fabrication methods that are electrically active in terms of sensing and actuation are invented. These materials are comprised of solid-state ion-conducting materials such as polyethylene oxide (PEO) and its derivatives or imbedded in a family of mixed polymer systems such as polydivinylbenzene (DVB) and polystyrene polymers. Such materials suitably electroded with conductive materials such as gold, platinum and silver exhibit large deformation (both two and three dimensionally) under low electric fields of 10's V/mm. Conversely, if these materials are deformed, they produce 10's of mV/mm electric fields that can be used as means of sensing or electromechanical powering devices for batteries. The method of fabricating the new polymeric materials comprises the steps of providing a polyelectrolyte material, mixing the polyelectrolyte material with a conductive material and affixing at least two electrodes to the mixed polyelectrolyte material and conductive material.
    • 发明了在感测和致动方面具有电活性的新的聚合材料及其制造方法。 这些材料由诸如聚环氧乙烷（PEO）及其衍生物的固态离子导电材料组成，或者嵌入到诸如聚二乙烯基苯（DVB）和聚苯乙烯聚合物的混合聚合物体系的系列中。 在10V / mm的低电场下，适当地用导电材料如金，铂和银电镀的这种材料显示出大的变形（二维和三维）。 相反，如果这些材料变形，它们会产生10 mV的mV / mm电场，可用作电池的感应或机电供电装置。 制备新聚合物材料的方法包括提供聚电解质材料，将聚电解质材料与导电材料混合并将至少两个电极固定在混合的聚电解质材料和导电材料上的步骤。

    • Implantable, pressure adjustable diaphragm pump systems which are scalable and are characterized by a common type of actuating mechanism. The pumps may be inductively and transcutaneously powered via adjacent, mutually inductive electromagnetic coils. Alternatively the pumps may be effectively “self” powered using a synthetic muscle attached to a local bending or twisting force. The pumps may be used in a range of applications from mechanical applications to medical applications such as intraocular pressure control for glaucoma patients, bodily fluid drainage control, and drug delivery systems. These pump systems each include a pumping chamber having an anterior end attached to an implantable influent conduit. In the case of an ocular pressure control device, the influent conduit is inserted into the anterior chamber of the eye. A flexing ionic polymer conductor composite IPCC synthetic muscle, which is a type of ionic polymer metal composite (IPMC) synthetic muscle, functions as the primary actuator. The posterior end of the pumping chamber is connected to an effluent or drainage conduit, which may drain bodily fluids or dispense drugs to an area of the body. A key feature of the invention is the self or secondary power generation system in the form of a much larger piece of IPCC synthetic muscle which, in the case of glaucoma prevention systems, may be placed on the globe surface (sclera) of the eye and attached to and secured by the extraocular muscles of the eye. An alternative external power system includes a biocompatible induction coil with gold wire armature that can be transcutanously activated, adjusted, and computer-interrogated and controlled by a surgeon. The device of the invention is further equipped with a pair of adjustable variable flow valves placed at the juncture of the inlet and effluent conduits with the pumping chamber. The valves are used to regulate fluid flow through the pumping chamber. A pressure regulating system including a pressure sensor and pump controlling microprocessor may also be used with the inventive system.

    • Surgical correction of human eye refractive errors such as presbyopia, hyperopia, myopia, and stigmatism by using transcutaneously inductively energized artificial muscle implants to either actively change the axial length and the anterior curvatures of the eye globe. This brings the retina/macula region to coincide with the focal point. The implants use transcutaneously inductively energized scleral constrictor bands equipped with composite artificial muscle structures. The implants can induce enough accommodation of a few diopters, to correct presbyopia, hyperopia, and myopia on demand. In the preferred embodiment, the implant comprises an active sphinctering smart band to encircle the sclera, preferably implanted under the conjunctiva and under the extraocular muscles to uniformly constrict the eye globe, similar to a scleral buckle band for surgical correction of retinal detachment, to induce active temporary myopia (hyperopia) by increasing (decreasing) the active length of the globe. In another embodiment, multiple and specially designed constrictor bands can be used to enable surgeons to correct stigmatism. The composite artificial muscles are either resilient composite shaped memory alloy-silicone rubber implants in the form of endless active scleral bands, electroactive ionic polymeric artificial muscle structures, electrochemically contractile endless bands of ionic polymers such as polyacrylonitrile (PAN), thermally contractile liquid crystal elastomer artificial muscle structures, magnetically deployable structures or solenoids or other deployable structures equipped with smart materials such as preferably piezocerams, piezopolymers, electroactive and eletrostrictive polymers, magnetostrictive materials, and electro or magnetorheological materials.
