Paper Abstract

Dielectric elastomer actuators offer unprecedented opportunities for actuation in a wide range of applications. To make appealing large scale and efficient systems, new electronic devices combining high voltage and flexibility need to be designed. In this paper we report the first mechatronic system, made of an array of electro-active polymer based actuators integrated with thin film photoconductive high voltage switches fabricated on a plastic film substrate. The actuator is an acrylic elastomer diaphragm that expands under electrical stimulation. Each actuator is connected to the high voltage power supply through a photoconductive switch, which is addressed and closed by illumination. The amorphous silicon switches are made on flexible and transparent polyimide (Kapton E®) substrates. Individual switches were tested up to 8 kV and a nine-element array was successfully working at 5 kV.
