Paper Title:
Performance of a Dielectric Elastomer Generator Diaphragm as a Smart Composite at Different Pre-Strain Levels
  Abstract

Dielectric elastomers (DEs) could be considered as a new type of transducers. They can convert electrical and mechanical energies in a bi-directional manner. In this work, the electromechanical behavior of a DE diaphragmatic generator was investigated. Circular diaphragms were fabricated using a prestretched DE film sandwiched between laminates of compliant electrodes. A special chamber was used to apply pressure. Pressure-Volume characteristics of diaphragms were measured to calculate elastic energy density. DC voltages were applied to the electrodes and the generated voltages were measured. It was concluded that efficiency of generators was strongly dependent on the amount of biased voltage, pre-straining level and applied pressures.
