DEVICE HAVING CONTROLLABLE ADHESION

摘要

The invention relates to a combination of a first device and a second device, wherein both devices comprise at least one surface and the surface of the first device comprises at least one recess. At least one contact surface is formed when the surface of the first device attaches to the surface of the second device. By applying external pressure, the adhesion force between the two devices can be switched back and forth between at least two states.
