Design and static modeling of a semicircular polymetric piezoelectric microactuator

The design of a piezoelectric-based microactuator to be used in the construction of an artificial hand is discussed. The microactuator is in the form of semicircular bimorph which consists of two layers of piezoelectric material connected electrically parallel. Several prototypes of this microactuator are tested through three different experiments. The results show that the microactuator's semicircular shape increases the force of the artificial hand.
