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.
