Self-Assembly of Micromachining Systems Powered by Janus Micromotors

The manipulation, transport, and assembly of microobjects is of paramount importance for microengineering and biological applications. Among the earliest approaches were microelectromechanical systems based microgrippers.[1, 2] They represent a very versatile tool that might be used for handling fragile objects from millimeter to micron size.[3, 4] Noncontact manipulation can be achieved by electrostatic actuators evolved from tip-like actuators [5] to cilia-inspired structures...
