  • Publication number: 20250123244
    Abstract: The invention relates to an ultrasonic sensor, which includes a housing. The housing is provided with a supporting part inside, as well as a connecting opening that connects to the outside environment. It also includes a first planar electrode and a second planar electrode, which are arranged on the supporting part and positioned opposite to each other. The first planar electrode is at least partially in contact with the second planar electrode, and both are insulated from each other to form a stable planar capacitor. The first planar electrode comprises an insulating film and a first conductive layer, which is arranged on one side of the insulating film. The second planar electrode comprises a conductive substrate. This ultrasonic sensor replaces the piezoelectric ceramic plate with the first and second planar electrodes to form a planar capacitor, thus avoiding the technical defects caused by the production technology of piezoelectric ceramic plates.
