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.
