Abstract
Provided is a novel actuator and a method for driving the same. The present invention is an actuator comprising a first laminate comprising a first (Bi, Na, Ba) TiOlayer between first and second electrode layers, a second laminate comprising a second (Bi, Na, Ba) TiOlayer between third and fourth electrode layers, and a tilt part provided between the first and second laminates. Both of the first and second (Bi, Na, Ba) TiOlayers are preferentially oriented in a [011] crystalline axis direction. Voltages V, V, V, and Vwhich satisfy Requirement A: V>Vand V<Vor Requirement B: V<Vand V>Vare applied to the first-fourth electrode layers so as to tilt the tilt part. One of the first edge and the second edge is moved in the [011] crystalline axis direction and the other is moved in the reverse direction thereof.
