Abstract:

A piezoelectric sensor having a plurality of electrodes deposited on a single surface of the dielectric medium is generally provided. The plurality of electrodes can define a plurality of square-shaped electrodes forming a grid on the first surface of the dielectric medium while the second electrode defines a continuous electrode. An electrode border surrounding the plurality of electrodes can be deposited on the first surface of the dielectric medium. Alternatively, the plurality of electrodes can define column-shaped electrodes, while the second electrode defines a plurality of row-shaped electrodes separated by etchings. The direction of orientation of each column-shaped electrode and the direction of orientation of each row-shaped electrode can be substantially perpendicular. A method of making a piezoelectric sensor is also provided.
