A) Resistance change at selected cycles (1 - 100). The zoomed-in box ‘A’ show a large drift in the sensor data in a strain interval of 0 % to 20 %. The zoomed-in box ‘B’ show a small drift in sensor data in a strain profile of 25 % to 45 %. B) Hysteresis of the actuator during passive actuation mode and the mean over cycles with a small drift error of 6%.
