We have studied adhesion type micro-manipulation with capillary force of tiny meniscus between an object and manipulator tip. Pipette type micromanipulator tip was previously studied, where adhesion force can be varied between l3μN to 0.8μN level due to wet and dry state change by water in the pipette spreading over the tip for low temperature condition and evaporation for high temperature condition over 120℃, respectively. The objective of this study is the development of micromanipulator tip controlling the adhesion force by small temperature variation near the room condition. So, we designed a double pipe type micromanipulator tip with cooling and heating functions. The adhesion force of the double pipe type tip is elevated by dew condensation with cooling by the J-T effect, and lowered by evaporation of the liquid film with heating with wound wire heater. As a result, it was shown that the new tip can varies the adhesion force between 20μN to 2μN levels with temperature change near the room condition. Also, fixation of the object on the tip after the heating process was observed.
