Abstract
While the proposed single probe gripper shows promise in picking up an object using strong capillary and surface tension forces, the main challenge has been the smooth release of the object. I'm proposing to Study on micromanipulation using EWOD. By controlling the electrical field imposed on the gripper surface, one can manipulate the contact angle of the liquid bridge and therefore, the meniscus geometry. Modifyin g the curvature of the meniscus geometry causes the lifting force between the object and the gripper to change. In order to explain the grasping of the object by the effect of the contact angle manipulation, I conducted an experiment in units of mm. As a result, it was possible to separate by the self-weight of the object and the wettability of the surface by operating the contact angle by application of EWOD.
