Electroactive polymers (EAPS) are polymeric materials that might undergo changes in shape and dimension as a response to an applied suitable electrical stimulus. They are a subclass of electroresponsive polymers, especially in electromechanical systems. EAPs are a subject of interest in engineering, science, and technology due their useful properties in numerous bioinspired, sensing, innovative generators, and technological applications. EAPs consist of a broad class of promising sensing materials; however, they are still a new concept for scientists that work in sensor-related research. Currenlty, no material can cover all sensory requirements, and the choice of material should be carefully chosen to fit the individual requirements.
