Abstract (en)
[origin: EP1902789A1] The transducer (1) has an adaptation layer (5) for acoustic impedance matching of a piezo-ceramic disc (3) at an environmental medium. The piezo-ceramic disc and the adaptation layer are embedded into a damping body (7). The layer is provided with a radiating surface (8), where a front side of the transducer with the radiating surface and a part of an upper surface of a cupular transducer housing (9) are coated with a parylene layer (11). The damping body is embedded into the transducer housing in such a manner that the radiating surface is free. Independent claims are also included for the following: (1) a method for manufacturing an ultrasound transducer (2) an ultrasound sensor comprising a housing (3) a method for manufacturing an ultrasound sensor.
