Controlling Droplet Vaporization/Condensation for Liquid Supply of Capillary-Based Micromanipulation

In this paper, an approach to condense micro droplet with aimed volume and to maintain its volume is shown. The approach is performed experimentally by means of controlled temperature sequence. Peltiert element was used to control the temperature of copper surface. Pico litter ordered droplet was observed and its volume was estimated by video image processing. From the heat balance analysis, the availability of condensation strategy and the guiding principle of the design of capillary-based micromanipulator are discussed.
