Abstract: Described herein is electroadhesion technology that permits controllable adherence between two objects. Electroadhesion uses electrostatic forces of attraction produced by an electrostatic adhesion voltage, which is applied using electrodes in an electroadhesive device. The electrostatic adhesion voltage produces an electric field and electrostatic adherence forces. When the electroadhesive device and electrodes are positioned near a surface of an object such as a vertical wall, the electrostatic adherence forces hold the electroadhesive device in position relative to the surface and object. This can be used to increase traction or maintain the position of the electroadhesive device relative to a surface. Electric control of the electrostatic adhesion voltage permits the adhesion to be controllably and readily turned on and off.

Abstract: The invention describes devices for performing thermodynamic work on a fluid, such as pumps (340), compressors and fans. The thermodynamic work may be used to provide a driving force for moving the fluid. Work performed on the fluid may be transmitted to other devices, such as a piston in a hydraulic actuation device. The devices may include one or more electroactive polymer transducers (341) with an electroactive polymer (341) that deflects in response to an application of an electric field. The electroactive polymer (341) may be used to perform thermodynamic work on the fluid. The devices may be designed to efficiently operate at a plurality of operating conditions, such as operating conditions that produce an acoustic signal above or below the human hearing range. The devices may be used in thermal control systems, such as refrigeration system, cooling systems and heating systems.

Abstract: The present invention relates to electroactive polymers (152) that are pre-strained to improve conversion from electrical to mechanical energy. When a voltage is applied to electrodes (156) contacting a pre-strained polymer (152), the polymer (152) deflects. This deflection may be used to do mechanical work. The pre-strain improves the mechanical response of an electroactive polymer (152). The present invention also relates to actuators including an electroactive polymer and mechanical coupling to convert deflection of the polymer into mechanical work. The present invention further relates to compliant electrodes that conform to the shape of a polymer. The present invention provides methods for fabrication electromechanical devices including one or more electroactive polymers.

Abstract: The present invention provides electroactive polymer transducers that produce out-of-plane deflections. The transducers form a set of surface features based on deflection of an electroactive polymer. The set of surface features may include elevated polymer surface features and/or depressed electrode surface features. Actuation of an active area may produce the polymer deflection that creates one or more surface features. A passive layer may operably connect to a polymer. The passive layer may comprise a thicker and softer material to amplify polymer thickness changes and increase surface feature visibility.

Abstract: The present invention provides electroactive polymers (40), transducers and devices that maintain pre-strain in one or more portions (42) of an electroactive polymer (40). Electroactive polymers described herein may include a pre-strained portion (42) and a stiffened portion (44) configured to maintain pre-strain in the pre-strained portion (42). One partially cured polymer is then further cured to stiffen and maintain the pre-strain. In another fabrication technique, a support layer is coupled to the polymer that maintains pre-strain in a portion of an electroactive polymer. Another embodiment of the invention cures a polymer precursor to maintain pre- strain in an electroactive polymer.

Abstract: The present invention provides meta-materials with an actively controllable mechanical property. The meta-material includes a deformable structure and a set of activation elements. The activation elements are controllable between multiple states. The meta-material includes a first value for a mechanical property when one or more of the activation elements is in the first activation state and includes a second value for the mechanical property when the activation elements have been activated to the second activation state. In one aspect, the meta-material resembles a composite material where the connectivity between the component materials or shape and arrangement of the component materials is dynamically controllable so as to affect a mechanical property of the meta-material.

Abstract: The invention describes devices for controlling fluid flow (306), such as valves. The devices may include one or more electroactive polymer transducers (308, 309) with an electroactive polymer (308, 309) that deflects in response to an application of an electric field. The electroactive polymer (308, 309) may be in contact with a fluid where the deflection of the electroactive polymer (308, 309) may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but not limited to, 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer (308, 309) may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer (308, 309) may be a portion of a surface of a structure used in an internal flow (306), such as a bounding surface of a fluid conduit (300).
