Characterization of Dielectric Electroactive Polymer transducers
Abstract
This paper analysis the small-signal model of the Dielectric Electro Active Polymer (DEAP) transducer. The DEAP transducer have been proposed as an alternative to the electrodynamic transducer in sound reproduction systems. In order to understand how the DEAP transducer works, and provide guidelines for design optimization, accurate characterization of the transducer must be established. The small signal model of the DEAP transducer is derived and verified. Impedance measurements are shown for a push-pull DEAP based loudspeaker, and the dependency of the biasing voltage is explained. <br/>A measuring setup is proposed, which allows the impedance to be measured, while the DEAP transducer is connected to its biasing source.
