Patent ID: 8646180

Claim:
A method of producing an electromechanical transducer, the method comprising: a first step of partially modifying a surface of a first electrode; a second step of applying a sol-gel liquid including a metal composite oxide to a predetermined area of the partially-modified surface of the first electrode; a third step of performing drying, thermal decomposition, and crystallization to the applied sol-gel liquid to form an electromechanical transduction film, wherein the drying includes a heat-treatment at 120° C., the decomposition includes thermal decomposition performed at 500° C., and the crystallization includes heat treatment for crystallization at 700° C.; a fourth step of repeating the first, second, and third steps to thicken the electromechanical transduction film to a desired thickness; and a fifth step of forming a second electrode on the electromechanical transduction film.
