Abstract
The purpose of this research is to develop the more compact human blood sampling system applied a micro-needle whose external diameter is less than 100 μm for a medical device of the Bio-MEM. The design concept of the prototype is the biomimetic micro-machine of female mosquito's blood sampling mechanism and the performance of the main mechanical elements are tested. Indentation force of the micro-needle whose head has grinded by a super fine grinding film, indentation stroke of the linear to-and-fro motion device using a shape memory (SMA) spring and fluid sampling ability of the micro-pump using a piezoelectric micro-actuator were measured.
