  • Piezoelectric plate electric connection structure
    Publication number: 20070210875
    Abstract: A piezoelectric plate electric connection structure aims to receive an input voltage from a voltage source and goes through a polarization process to deliver an output voltage. It has an input electrode on a piezoelectric plate to receive input from the voltage source and an output electrode to deliver the output voltage that are located on two surfaces normal to the polarization direction. One surface has an independent electrode. Another surface has two separated electrodes. The input electrode and output electrode are respectively the independent electrode and one of the separated electrodes. The input and output electrodes are spaced by the piezoelectric plate which is dielectric and pressure-resistant. Thus discharge phenomenon can be prevented between the input electrode and the output electrode.
