| Research Abstract |
In order to develop a micro vacuum pump, basic experiment has been carried out from following four standing points of view.
1) In order to measure the pressure in the micro space, an optical vacuum gauge using a photothermal effect has been developed by fabricating a micro cantilever with a micromachining technique. The pressure in the low vacuum region can be determined exactly with measuring the resonance frequency of the canti-lever. The theoretical analysis was also performed.
2) An optical miniature actuator for driving the pump has been developed utilizing a shape-memory alloy. With the irradiation power of 300 mW, the displacement of 3 mm and the generative force of 2.2 N were obtained.
3) The micromachining technique was applied to the fabrication of the micro vacuum gauge. A micro photolithography for etching metals was used for making the miniature pump.
4) The miniature pump for flowing liquid was drived by the optical minature actuator. The flow rate of 140 ul/min was obtained. The pumping up pressure and the pumping out pressure were 1000 and 1500 mmH_2O, respectively.
