Paper Abstract

In this paper we report on the development of a high frequency switching amplifier for electrostrictive actuators. This amplifier is specifically designed for the capacitive loads that electrostrictive actuator present to them. One of the ultimate goals is to miniaturize these amplifiers so that they could be embedded into the material along with the actuators. Therefore, the configuration was chosen that would allow for miniaturization. The amplifier is also designed for high efficiency for thermal management. An integrated nonlinear model of the actuator and the electronics is also developed. A prototype Smart Material was fabricated consisting of sixty four actuators and sixteen amplifiers. Both experimental and simulation results of the Smart Material are reported.
