Abstract

The present invention is a micro pump which provides enhanced pumping ability. The structure of the present micro pump has a pumping portion which has a relatively larger deformation. According to the present invention, the disclosed pump allows for less loss of voltage and backward reflux flow of pumped fluid, and has greater pumping power and enhanced biocompatibility. The present invention is utilized with excellent potential in use with uTAS that control small amounts of fluid, medical apparatus for insertion into human bodies, and for adhesive processes in micro factories.
