Abstract
Research on lead-free piezoceramics has dramatically increased over the last years due to stringent legislation demanding to phase out current lead-containing piezoceramics. The use of electrostrictive materials for electric-field induced strain has been largely overlooked. in this paper we demonstrate that electrostrictive materials around a ferroelectric-antiferroelectric transition are capable of providing high strains over a wide temperature regime that was not accessible before.
