Paper Abstract

Piezoelectrics have been around for decades as acoustic or sensing components. In the last few years, however, they have seen increasing use as means to provide motion and control in the micron realm, well below the resolution level of mechanical or electromechanical devices. Their high hysteresis (15 - 20%), however, was a problem in some systems, and this led to the development of electrostrictive materials, which reduced that hysteresis by an order of magnitude, but at a cost of other parameters. The purpose of this paper is to compare the properties of each of them, without favoring one or the other.
