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.
