ABSTRACT:
A gripping apparatus for gripping and releasing objects and for use with a micromanipulator. Spaced cantilever jaws extending in substantially the same direction from a support are each formed of a pair of elongated ribbons of piezoelectric polymer bonded together in oppositely polarized orientation. An electrically conductive thin film is bonded to the outer surfaces of the laminate. A voltage is applied to the conductive films causing the polymer ribbon laminates to bend toward or away from each other dependent upon the polarity of the applied voltage so that they grip an object.
