Figure S5. Blocked force versus strain characterization setup of circular-type actuators. (a) Initial load (8.8 g: same as the weight of the PTFE sheet used in strain measurement setup) is applied to the actuator without an applied voltage. (b) 10 kV is applied by fixing the position of the load cell and the blocked force is measured. (c) Load cell position is elevated and the blocked force is measured by maintaining a 10 kV voltage supply.
