Piezoelectric actuator device |
摘要 |
A piezoelectric actuator, which has a large displacement rate and a relatively simple structure, is capable of providing an output without the need for a specific support and can be manufactured at low costs, is provided. The piezoelectric actuator 10 takes a planar plate-like form and has first and second layer regions 11 and 12 lying one upon the other. The first layer region 11 is formed comprising a piezoelectric ceramic material and contains electrodes 13-1 to 13-n for receiving an actuation voltage to cause this first layer region to contract in a plane parallel thereto. The second layer region 12 is formed integrally with the first layer region 11 and comprises a ceramic material.
