    摘要： The present invention relates to electroactive polymers that are pre-strained to 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. 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 fabricating electromechanical devices including one or more electroactive polymers.

    摘要： The invention relates to systems and methods for electrically communicating with an electroactive polymer using one or more electrodes that do not contact the polymer. A non-contact electrode communicates charge to or from a portion of the polymer, typically through a medium. For example, the medium may include air, a vacuum, or a specialized gas that facilitates transfer of charge between the electrode and the polymer. The charge may include positive or negative ions or electrodes and may act to actuate the polymer, or diminish actuation applied to polymer in one or more specific polymer portions.

    摘要： An electroadhesive device includes an outer surface adapted to interface with a surface of a foreign substrate, a plurality of electrodes, and a semi-conductive insulation material disposed adjacent to at least one of the electrodes. Each electrode has a respective conductive volume and is configured to apply a voltage at a respective location of the outer surface, and the difference in voltage between applied voltages includes an electrostatic adhesion voltage that produces an electrostatic force between the device and the substrate that is suitable to maintain a current position of the device relative to the substrate. The insulation material can be polyurethane or any other suitable material having a resistance of about 109 to 1012 ohms*m. The insulation material effectively operates to expand the conductive volume of the electrodes when they are actuated.

    摘要： 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.

    摘要： 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.
