ABSTRACT:
A linear actuator using a metal beam-type piezoelectric material, and an apparatus and a method for actuating the same. The piezoelectric actuator includes: a moving member having a predetermined length and moving in a forward or a backward direction; and a piezoelectric portion contacting the moving member and moving the moving member linearly using a vibration generated when a piezoelectric element contracts or expands in response to an electrical signal.
