Abstract :
A new vacuum-capture method was presented to pick and place the sample exactly for bio-microdissection. The main forces acting on micro-objects were analyzed and some equations of operation force condition were derived. A proportional valve and a fine pressure sensor were added to the vacuum unit to improve its pick and place capability. The measured operation pressures were controlled as the feedback signal by the vacuum unit based on closed-loop control. The good effect was gotten by the united control of PC and date traffic card to adjust the operation press. Experimental results validate the pick-place performance of vacuum-capture method based on closed-loop control for bio-microdissection
