Actuators

This silicone heater was made of the same material as the actuator but was combined with expandable pre-prepared dry graphite (Sigma-Aldrich, St. Louis, MO, USA) to create 25–65 Ω soft heaters. The soft heater samples were able to match and outperform the Ni-Cr heater samples in force exertion, achieving up to 200 N and 300 N of blocked force.
