3. Results and Discussion 3.1. Bending Characterization of the Silicone Arm Figure 7A–D show the bending angle of the tip of the arm vs. time for the currents used. As expected, a higher bending angle is caused by actuating the SMA with a higher current and a corresponding higher heating time. However, as can be seen in Figure 7B, the bending angle peaks at a minimum current of 1.25 A and a corresponding minimum time of 3 s. The maximum bending angle achieved is about 48°, as can be seen in Figure 7.
