摘要: A wall-crawling robot or other electroadhesive device can include a battery or other low voltage power source driving a motor that provides a primary device function, a voltage convertor adapted to convert the low voltage to a high voltage using the motor output, and electrodes configured to apply the high voltage to produce an electrostatic force between the electroadhesive device and a foreign substrate. The electrostatic force maintains a current position of the electroadhesive device relative to the foreign substrate, and the voltage convertor is separate from the primary function of the electroadhesive device. The primary function can be a mechanism for locomotion, and the voltage convertor can be a Van de Graff generator, a piezoelectric generator, or an inductive switch generator, any of which are driven in a secondary manner as a result of the motor output.

摘要: 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.

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: Described herein are compliant electroactive polymer transducers for use in acoustic applications. A compliant electroactive polymer transducer includes a compliant electroactive polymer at least two electrodes. For sound production, circuitry in electrical communication with the transducer electrodes is configured to apply a driving signal that causes the electroactive polymer to deflect in the acoustic range.

摘要: Described herein are several solutions that increase transducer lifetime by reducing or preventing tear propagation in a compliant electroactive polymer. One solution couples a compliant tear resistant treatment to a transducer proximate to an edge portion of the electroactive polymer. Another solution uses a tear resistant layer that couples to and covers a large surface area of the transducer. Another suitable tear resistant solution provides added material outside an active area; the added material reduces stress or strain variations in polymer material outside the active area when the electroactive polymer transducer is deflected or pre-strained
