Abstract
Based on Coulomb forces, electrostatic attraction is a type of actuation that can find many applications for electroactive devices. Electroactive polymers (EAP) are electric responsive materials with specific mechanical and electrical properties that make them promising for an efficient use of this phenomenon. This paper reports on the identification and experimental validation of Figures of Merit (FoM) of electro-adhesion effect for a normal and tangential solicitation. These actuation possibilities are suitable for different kinds of displacement (linear or circular motion) and modulation of shape-shifting designs including origami structures. Several EAP are used to determine the accuracy of experimental benchmarks for the evaluation of these different FoM. The results demonstrate that the developed experimental benchmarks are able to provide accurate values in a range of electric field of [0-5] V/μm. For higher electric fields, different events can occur, at both macroscopic and microscopic scales, leading to a slight decrease of expected performances.
