Abstract: This chapter explores the converse of the flexoelectric effect: an electric field applied across a bent-core liquid crystal sandwiched between thin flexible substrates produces a director distortion which is manifested as a polarity-dependent flexing of the substrates.The flex magnitude is shown to be consistent with predictions based upon both the measured value of the bend flexoelectric constant and the elastic properties of the substrates.Converse flexoelectricity makes possible a new class of micro-actuators with no internal moving parts, which offers applications as diverse as optical beam-steering to artificial muscles. 3.1
