Abstract: Combustion devices described herein comprise a compliant combustion chamber wall or segment. The compliant segment deforms during combustion in the combustion chamber. Some devices may include a compliant wall configured to stretch responsive to pressure generated by combustion of a fuel in the combustion chamber. A coupling portion translates deformation of the compliant segment or wall into mechanical output. One or more ports are configured to inlet an oxygen source and fuel into the combustion chamber and to outlet exhaust gases from the combustion chamber.

Abstract: Workstation, apparatuses and methods for the high-throughput synthesis, screening and/or characterization of combinatorial libraries. The invention relates to an array, which permits various high-throughput methods for synthesis, screening and/or characterization in the same array, without requiring sample transfer from the array. In a preferred embodiment, the synthesis, screening, and/or characterization steps are carried out in a highly parallel fashion, where more than one compound is synthesized, screened, and/or characterized at the same time. The invention may be practiced at the microscale. The array may comprise thermal channels, for regulating the temperature of the wells in the array. The wells of the array may comprise a membrane, which is used in various screening and characterization methods. The invention also relates to a covered array, comprising the array and an array cover, as well as an apparatus comprising the array, which comprises the array, an array cover and a stage.

Abstract: Disclosed generators includes one or more transducers that use electroactive polymer films to convert mechanical energy to electrical energy. The generators may include one or more transmission mechanisms that transfer a portion of an unused biological energy source, an unused environmental energy source or combinations of both to the one or more transducers located in the generators. The energy received by the transducers may be converted to electrical energy by the transducers in conjunction with conditioning electronics located within the generator. A heel-strike generator is disclosed that is integrated into the heel of footwear and is used to convert mechanical energy generated during human bipedal motion to electrical energy.

Abstract: An electroluminescent device and a method for producing the electroluminescent device are described. The device is formed from a layered structure comprising a hole-injection electrode layer for injecting holes into an electroluminescent material, an electron-injection electrode layer for injecting electrons into an electroluminescent material and a dielectric layer interposed between the hole-injecting and electron-injecting electrode layers. A cavity extends through at least the dielectric layer and one of the electrode layers and has an interior cavity surface comprising a hole-injection electrode region, an electron-injection electrode region and a dielectric region. An electroluminescent coating material is applied to the interior cavity surface in order to electrically contact the hole-injection and electron-injection electrode regions of the interior cavity surface.

Abstract: Pre-strained electroactive polymers are described that improve conversion from electrical to mechanical energy. When a voltage is applied to electrodes contacting a pre-strained polymer, the polymer deflects. This deflection may be used to do mechanical work. The pre-strain improves the mechanical response of an electroactive polymer. Also described herein are actuators that include an electroactive polymer and mechanical coupling to convert deflection of the polymer into mechanical work. Further described are compliant electrodes that conform to the shape of a polymer. Methods for fabricating electromechanical devices including one or more electroactive polymers are also described.
