The Circular Piezo Actuator is constructed with a substrate and one (Unimorph) or two (Bimorph) Piezo disc(s) by binding. Once it is subjected to a sine wave, which will cause piezo disc to expand or contract, the form of displacement will be similar to a sine wave. In the application of pump this action will cause pressure differences in between the inside and outside of the chamber, thus pushing the fluid to move.
