Abstract
Self sensing actuator system using a piezoelectric actuator device allows the device to perform both as an actuator and sensor. The sensor functions can be either measurements of stress or measurements of strain. The actuator can be used as a force generator or positioning device, both in open and closed loop configurations, and is useful for purposes ranging from dynamic damping to shape control (i.e., shaping or controlling deformation of a body).
