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.
