摘要： In accordance with one embodiment of the present application, a piezoelectric diaphragm structure includes a diaphragm, with a piezoelectric material located on the diaphragm. The piezoelectric material is being poled in a radial direction to the piezoelectric material, wherein the poling direction is in-plane with the piezoelectric material. An inter-digitated electrode grid is positioned on a first surface of the piezoelectric material, the inter-digitated electrode grid including a plurality of electrodes configured to selectively receive positive and negative voltage. The application of the positive and negative voltages generate electric fields in the piezoelectric material, at least a portion of which are in-plane with the piezoelectric material, resulting in an actuation of the piezoelectric material, causing a length change of the piezoelectric material in the Radial direction.In accordance with another embodiment of the present application, provided is a method of actuating a piezoelectric diaphragm structure, including poling a piezoelectric material in a radial direction of the piezoelectric material, wherein the poling direction is in-plane with the piezoelectric material. The piezoelectric material is located in operative contact with the diaphragm, and an electrode arrangement located on a surface of the piezoelectric material is selectively supplied with voltages generating electric fields. The generated electric fields are at least partially in the same plane as the poling direction, resulting in a d33 mode of actuation of the piezoelectric material, causing a length change of the piezoelectric material in the Radial direction.

摘要： A multi-electrode piezoelectric diaphragm structure includes a diaphragm, piezoelectric material located on the diaphragm, which is defined as having a first area, and a second area. The first area of the piezoelectric is poled in a first direction, and the second area of the piezoelectric is poled in a second direction. The poled first direction is in a Z-axis of the piezoelectric and the poled second direction is in a Radial axis of the piezoelectric. A first electrode is positioned in the first area, on the first surface, of the piezoelectric. A second electrode is positioned in the second area, on the first surface, of the piezoelectric. A third electrode is located on a second surface of the piezoelectric. The application of voltages to the first, second and third electrodes generates electric fields in the piezoelectric material resulting in actuation of the piezoelectric material, or the application of pressure or strain to the diaphragm generates electric potentials at the first, second and third electrodes.

摘要： A system and method of operation is described which utilizes an array of piezoelectric actuators distributed over the surface of a diaphragm. In one embodiment, the piezoelectric actuator array is used to cause a net motion of the diaphragm equal to the sum of the motions of each individual sub-chamber diaphragm. The system can be used as a sensor where a common motion applied to the sub-chamber diaphragm causes a net charge equal to the sum of the charges on each piezoelectric diaphragm.
