Abstract

An optically driven actuator is a non-contact method for the remote application of light energy. A new method for optically driving actuators which uses a polyvinylidine difluoride (PVDF) cantilever is proposed. The PVDF cantilever is coated with silver on one surface. The PVDF is a ferroelectric polymer that has both pyroelectric and piezoelectric properties. When one side of the cantilever is irradiated by a laser beam, an electric field is produced along cross-section of the cantilever and mechanical displacement occurs by the piezoelectric effect. The response of the PVDF cantilever is analyzed mathematically.
