A piezoelectric micro-pump with difference from the conventional pump in working principle and configuration was presented for pumping minutely in medicine. The pump prototype was designed and manufactured in laboratory, and a special power supply was made in order to obtain the method and rule for controlling precision pumping. By the systemic experimental research, it is concluded that the micro-pump has a stable work performance and precision pumping property, and is suitable for the microminiaturization. It can provide a useful reference for the development of micro-pump in practice and precision.
