*Abstract

Researchers at the University of California, Berkeley have developed an apparatus for manipulating micro-scale objects. At the micro-scale level, adhesion forces of surface tension, and electrostatic and Van der Waals force dominate gravitational forces. Recent work has shown how adhesive forces can be used advantageously during microassembly tasks by controlling contact areas and surface tension, to ensure that microparts are reliably transferred to the target surface and released from a gripper.
