Abstract
An actuator has: a piezoelectric body formed in a shape of a tube and having an inner side wall, which faces a hollow portion of the tube, and an outer side wall, which is structured at an outer side of the tube; a first electrode formed at the inner side wall of the piezoelectric body; and a second electrode formed at the outer side wall of the piezoelectric body. The actuator displaces the piezoelectric body by a potential difference between the first electrode and the second electrode.
Claims18
An actuator comprising:
- a piezoelectric body formed in a shape of a tube and having an inner side wall, which faces a hollow portion of the tube, and an outer side wall, which is structured at an outer side of the tube;
- a substrate to which one end of the tube of the piezoelectric body is fixed;
- a first electrode formed at the inner side wall of the piezoelectric body;
- and
