ELECTROMECHANICAL TRANSDUCER |
摘要 |
When the initial displacement greatly varies among cells in an element, there is a need to reduce a bias voltage to be applied between electrodes. This decreases the sensitivity. An electromechanical transducer of the present invention includes an element having a plurality of cells. Each of the cells includes a first electrode and a second electrode that are provided with a cavity being disposed therebetween. A groove is provided at a position at a predetermined distance from the cavity of the cell on the outermost periphery of the element.
