Ultrasonic sensor |
摘要 |
An ultrasonic sensor which is particularly suited to measuring the sound-pressure amplitude in the focus range of a lithotripter and includes in a region a piezoelectrically activated polymeric foil, which is coupled to electrodes. The polymeric foil is mounted in a housing, which has a convex curved, dome-shaped surface at least in one region located opposite one of the flat sides of the polymeric foil. A simple measurement of the sonic field is thus made possible directly on the rubber-diaphragm encased, water-filled delay path of the lithotripter.
