Abstract
A method for deforming materials which are ferroelectric, have remanent polarization, and which exhibit a length-dependent photoelectric effect. One type of material is photovoltaic, piezoelectric, ferroelectric ceramics. Illuminating such materials causes them to deform, either in length or in thickness, depending on the direction of the remanent polarization. A single plate of such material may be used, or a pair of plates bonded together may be used.
