Conducting polymer actuators are of interest due to their low voltage operation, and their relatively high strains and forces. However, information is incomplete regarding the appropriate operating loads, the extent of creep and cycle life. We report

Poly(3,4-ethylenedioxythiophene), or PEDOT, freestanding films were synthesized and characterized as conducting polymer linear actuators. Variations of solvent and electrolyte led to the observation of strains greater than 4% with maximum strain rate

A typical limitation of polypyrrole based conducting polymer actuators is the low achievable active linear strains (2 % recoverable at 10 MPa, 7 % max) that these active materials exhibit when activated in a common propylene carbonate / tetraethylamm
