Piezoelectric polymer microgripper

摘要

Improved microgrippers using piezoelectric polymers are disclosed utilizing a pair of levers formed in a plier-like structure having piezoelectric polymer composite sheets connected between the levers or between each lever and a third intermediate lever or through a drive linkage to the levers. By appropriate application of electric fields, jaws formed at the ends of the levers are moved toward and away from each other to accomplish the grasping and releasing action.
