Abstract

This paper introduces a piezoelectric micro-pump with a new structure based on lamination

which adopts a cantilever check valve. In the laboratory the prototype pump has been designed and manufactured

the sine wave signal forming schematic circuit has been finished

which used to drive the micro pump after power amplification and voltage amplification. The systemic experiment research also has been done

the optimization project has been put forward

which adopts multi-chamber series connection structure to improve the performance of micro-pump. Through a series of experiments and tests

many beneficial conclusions have been drawn. the micro-pump possesses the stable work performance and owns higher ratio of performance to volume(the apparent dimension of pump:

15 mm×1.8 mm; the maximal low rate and backpressure of the micro-pump are about 3.6 ml/min and 22 kPa when applying 50 V sine wave driving voltage at 80 Hz). The structure and manufacture processing are useful for the design and development of the applied piezoelectric micro-pump.
