Paper Abstract

We report on the performance of micromachined unimorph actuators (PMAT) based on the electrostrictive poly(vinylidene fluoride-trifluoroethylene) copolymer. Because of the high electrostrictive strain and high elastic energy density of the active polymer, the PMAT exhibits a very high stroke level with high load capability and high displacement voltage ratio. In addition, the experimental data also demonstrate that the PMAT is capable of operating over a broad frequency range. The PMAT performance was modeled and the agreement between the modeling results and experimental data confirms that the response of the PMAT indeed follows the design parameters.
