摘要： An actuator driven by a smart material device and suitable for use as an actuator, energy capture device, or sensor, having an enclosed compensator, potting material, at least one actuating arm, and two mechanical webs and a movable supporting member adapted such that application of a suitable electric potential causes a change in shape of the smart material device, thereby flexing the mechanical webs and causing movement of the actuating arm. As an energy capture device or sensor, external motion causes the actuating arm to move, thereby causing the smart material device to generate recoverable electrical energy or an electric signal indicating motion.

摘要： The present invention includes a method of compensating for differences in the rate of thermal expansion in one or more elements of an electromechanical actuator. The electromechanical actuator can include one or more elements such as a piezoelectric ceramic multilayer actuator (CMA) and a mechanism to amplify the motion of the CMA. A difference in the rate of thermal expansion or coefficient of thermal expansion, CTE, between the materials in the CMA and the amplifying mechanism can cause the two components to vary in size at differing rates as the ambient temperature varies. Since the amplifying mechanism provides substantial amplification of the motion of the CMA, the relative variation in size of the components due to temperature can be translated by the amplifying mechanism as motion of the CMA. This can result in substantial motion of the amplifying mechanism. Replacing a mechanical element in the amplifying mechanism with an element having a different value for the CTE substantially reduces the difference in CTE of the materials, thereby reducing the thermally induced motion of the amplifying mechanism. Further, the material used and the means of interconnecting the replacement element in the amplification device for thermal compensation can maintain high rigidity of the CMA support structure, since the support structure transmits the motion and force of the CMA to the amplifying mechanism as well as applying a compressive preload to the CMA. Further, a high level of compressive preload force can be used as an additional part of the overall design process to adjust the degree of thermal compensation required.
