This paper presents the results of experimental characterization of an Amplified Piezoelectric Actuator (APA) under quasi-static operation. The data obtained from the study will be used for designing a control system for a microgripper which will be actuated using the APA. An improved measurement method suited for static force measurement was devised. The study identified relation between force applied by the piezo-actuator in relation to the applied voltage and resultant displacement which is presented in the form of a 3D graph. These relations are necessary for performing optimized microgripper movement and grasping.
