This heating cycle is undergone 20 times
until the resting length converges. At this point, applying
voltages to this newly-constructed SCP actuator will cause
the actuator to contract. Maximum contraction for the 117/17
condutive thread used was approximately 10% before the
thread burned out. In order to prevent the SCP actuators
from untwisting, 2-plys were formed (Figure 1b) from singleply
coiled threads (Figure 1a). The resultant rest length at
ambient temperatures Tamb = 25 was 100 mm.
