Devices using a ceramic piezoelectric

摘要

An electromechanical vice includes a support structure, a component moveable with respect to the support structure, and a piezoelectric device mechanically coupled to both the support structure and the component. The piezoelectric device includes a polycrystalline body and electrodes located on the body. The body has a composition with a stoichiometry described by [Pb(Mg1/3Nb2/3)O3](1-x) [PbTiO3]x. The value of x is in the range of about 0.31 to about 0.47.
