Electronically conducting polymer (ECP) actuators and sensors are ionic EAPs, whose working principle relies on the motion of ions, usually contained in an electrolyte, toward or from the electroactive polymer. We demonstrate here that linear deformation and sensing in open-air are accessible for ionic EAPs if classical trilayer devices are made electromechanically asymmetric by tuning the properties of PEDOT:PSS electrodes according to an electromechanical model. We also present the first results on “dry” ionic conducting membranes based on polymeric ionic liquids. This “dry” electrolyte allows developing ionic EAPs without any liquid component and still presenting large and fast bending deformation
