The transducer (3) has plate-shaped flexible transducer element (4) formed with piezoelectrically activated working section and two wide sides. An electrical conductor structure (32) is formed on a flexible substrate (28) to form a flexible printed circuit (27) that electrical contacts work section of transducer element by piezoelectric activation. Part of the electrical conductor structure is formed within the region of the work section of the transducer element. Sensors (38,39) are provided in the work section of the transducer element and flexible printed circuit to detect change of state. |
