Paper Abstract

Polymeric actuators, electroactive polymer actuators, electromechanical polymeric actuators, artificial muscles, and other, are usual expressions to name actuators developed during the last 15-20 years based on interactions between the electric energy and polymer films. The polymeric actuators can be divided into two main fields: electromechanical actuators working by electrostatic interactions between the polymer and the applied electric fields, and electrochemomechanical actuators, or reactive actuators, working by an electrochemical reaction driven by the flowing electric current. The electromechanical actuators can be classified into electrostrictive, piezoelectric, ferroelectric, electrostatic and electrokinetic. They can include a solvent (wet) or not (dry), or they can include a salt or not. Similitude and differences related to the rate and position control or to the possibility or not to include sensing abilities are discussed.
