MicroTweezers Tip Four Point Grip

MEMS Precision Instruments

This tip provides 4-point contact with the object being gripped. Each of the 4 independently compliant tips will come into contact with a point on the object's surface when the tweezers close. This enables the gripper to resist applied monemts that would otherwise act to rotate the object. The beams of the tip are 2 microns wide. The small bumps located along the length of the beams are called anti-stiction dimples, and prevent the beams from becoming permanently stuck together due to surface tension of drying water after using the tweezer in water (or another liquid).
