1. An electromechanical transducer having a layered structure comprising in this order:
a first layer which has, in at least one plane, at least one outwardly insulated, structured, electrically conductive region acting as an electrical shield;
a second layer serving as an adhesive layer, which is electrically conductive at least at certain points;
a third layer comprising a piezoelectric sensor that generates a signal responsive to mechanical pressure;
a fourth layer serving as an adhesive layer, which is electrically conductive at least at certain points;
a fifth layer comprising a piezoelectric sensor that generates a signal responsive to mechanical pressure;
a sixth layer which has, in at least one plane, at least one outwardly insulated structured electrically conductive region acting as an electrical shield, wherein at least one of the first layer and the sixth layer has a contact exposed on the outside.
