| 摘要 |
Electromechanical transducer element for converting mechanical stress into electrical signals, said transducer comprising: at least one transducer elements ( 119,120 ), said element having first and second surfaces; at least one signal electrode layer ( 209 ) arranged between two transducer elements, said signal electrode layer being a metal layer arranged in direct contact with first surfaces of the two transducer film elements. Bosses may be arranged adjacent to and/or partly onto at least one electrode layer. The invention relates also to a manufacturing method where adjacent to and/or partly onto a signal electrode and/or a ground electrode a thicker layer of isolating material is deposited, or for composition of the film bosses are arranged in the signal and/or ground electrode.
