Design and simulation of piezoelectric micropump for a constant flow rate

A micropump is just like any other ordinary pumps except that it deals with fluids in extremely small dimensions. It works based on the concept of suction and decompression. The challenges faced in designing a piezoelectric micropump are to have a controlled flow rate as well as increasing the effic...
