The manipulation of small objectives becomes difficult with a miniaturization, because surface force such as electrostatic force, Van der Waals force and meniscus force becomes dominant than body force such as gravitational force in micro- and nanoscale. Thus, the micromanipulation requires a suitable control of adhesion force between the objective and a manipulator tip. In this study, we focused the meniscus force causing the adhesion phenomenon and invented a thermal control method of adhesion and detachment of the micro object. Meniscus tip was made by winding heater on a sharpen capillary tube. The dry and wet states of the Meniscus tip can be controlled by filling the capillary tube with water and heating near its tip. The controllability of the adhesion force was quantitatively confirmed with an adhesion force meter. Additionally, the micromanipulation of small glass beads was demonstrated.
