Design and characteristic analysis of a piezoelectric micro-jet generator
Fifth Asia International Symposium on Mechatronics (AISM 2015), 2015Considering the lubrication failure of spacecraft, an original piezoelectric micro-jet device which takes the control moment gyro (CMG) as specific application object is proposed. The working principle of the micro-jet device was analyzed. The structure designs were illustrated detailedly.

Fabrication and Basic Characterization of a Piezoelectric Valveless Micro Jet Pump
Japanese Journal of Applied Physics, 2008A piezoelectric-driven valveless micro jet pump with a novel channel structure has been designed and fabricated. The simple structure micro jet pump consists of a lead zirconate titanate (PZT) diaphragm and flow channels. The design of the flow channels focuses on a cross junction formed by the neck of the pump chamber and one outlet and two opposite ...
