The Design and Research on a New Piezoelectric Torsion Actuator

A new type of torsion piezoelectric actuator is designed to simplify the structure and improve the efficiency of energy. With the bending of the piezoelectric bimorph in the electric field, the torsion displacement is achieved. By laser reflection, the small angle is measured;and the finite element analysis and the test results are compared. The test research shows that it is feasible to produce a piezoelectric torsion actuator with this method, and the error analysis provides a theoretical basis for further optimization.
