<p>The transducer device (2) has layered composite (4) that is arranged between electrodes (6,8). The layered composite comprises electro-active layers (10,12). An electret material (14) having predetermined electrical charge is provided between the electro-active layers. An operating point of electro-mechanical transducer device is adjusted depending on the electric charge of electret material. Independent claims are included for the following: (1) electromechanical transducer system; and (2) method of producing electromechanical transducer device.</p> |
