ABSTRACT:
A piezo electric film has a signal electrode on one side of the film and a primary ground electrode on the other side of the film. The signal and ground electrodes are for connection to external conductors that process the electrical signals of the piezo film. In order to facilitate connection of the ground electrode to an external ground conductor, a secondary ground electrode is provided on the same side of the film as the signal electrode. The secondary ground electrode is capacitively coupled to the primary ground electrode. This arrangement enables connection of signal and ground conductors to the electrodes from one side only, which, for example, enables the piezo film to be mounted on a printed circuit board directly in contact with conductive circuit traces. An industrial application may be for piezo electric transducers, such as used in liquid level sensors.
