Abstract:This assignment aimed to characterize a prototype of a variable sti�ness actuator based on the piezoelectric material Polyvinyldi uoride (PVdF). An existing actuator was mod- i�ed and a measurement setup was built around it. It was able to measure the force the actuator could output for di�erent angles between the input and output ring. Data obtained from the experiments was processed into the output torque the actuator exerts for applied voltages of 0V, 200V and 400V.
