Abstract
Official abstract text for this publication.
The invention provides circuits, systems and methods for dielectric elastomer device (DED) self-sensing. The circuit comprises a first DED coupled or adapted for coupling to a first voltage source (for providing an actuating or priming signal, for example); a current sensor provided in series with the first DED; and an oscillating signal source coupled to the first DED and adapted to cause an oscillation in a voltage across the DED, wherein the oscillating signal source is decoupled from the first voltage source.
