The work by Kornbluh, Higuchi [4]and others was also significant in that it suggested that electrostatic forces on micro scales might be used for such artificial muscles. Indeed, it is fair to say that dielectric elastomers might never have been discovered as a technology without the observation by many micro-electromechanical systems (MEMS) researchers that very small gaps, and very thin films, can have much higher electric breakdown strength than corresponding macro structures.
