]]> Non-contact manipulation is a way to perform micro-objets positioning without adhesion perturbations. This video shows a top view of a non contact micromanipulation using negative dielectrophoresis (DEP). The microgripper’s end-effectors are in silicon with gold electrodes, and the manipulated gl balls are around 20µm diameter. An alternative tension (20V p-p) is applied between electrodes on each end-effectors to applied a negative DEP force on the object.

]]> During micromanipulations, release is disturbed by adhesion effects and negative dielectrophoresis (DEP) can be used to actively release the object. The video presents a top view of an active release. The microgripper’s end-effectors are in silicon with gold electrodes, and the handled ball is a 20µm gl ball. An alternative tension (20V p-p) is applied between electrodes on each end-effectors to applied a negative DEP force on the object.
