<p>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; and at least two ground electrode layers (211, 212), said ground electrode layers being metal layers arranged in direct contact with second surfaces of the 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 compression of the film bosses are arranged in the signal and/or ground electrode.</p> |
