  • Piezoelectric pressure sensor
    Patent number: 10330550
    Abstract: A piezoelectric pressure sensor includes a membrane for capturing a force; a piezoelectric transducer having a front face onto which the force is applied from the membrane and generates electric polarization charges; and an electrode that receives generated electric polarization charges and transmits them via a charge transmission. The electrode includes a charge pick-off and at least one electrode strip. The charge pick-off is arranged parallel to the front face of the piezoelectric transducer. Material bonding in certain areas of the electrode strip connects the charge transmission to the electrode strip.
    Type: Grant
