Paper Abstract

Recently, micro-actuators are attracted attention of advance technology. An optical actuator features characteristics such as energy supplied remotely in wireless and no generation of magnetic noise. In this report, a new type of a micro bubble actuator using photo-thermal effect is proposed The micro bubble by photothermal effect has advantage that to appear and disappear is easily to control. It is possible to drive micro-scale objects and an optical switch. An experimental set up consists of a laser diode with 450mW of power, water road and an optical microscope as observation. The micro bubble is produced irradiated laser beam on to black liquid and/or transparent liquid on the black surface. The size of micro bubble is from 50 to several hundred micro-meters. Three difference methods are proposed such as driving micro object, rotating micro object, and switching.
