Super Stretchable Soft Actuator made of Twisted and Coiled Spandex Fiber

摘要

Twist and Coiled soft Actuator (TCA) is simply fabricated by twisting a polymer fiber. In the previous researches, TCA was mainly fabricated with Nylon 6,6 fiber, and Nylon-TCA (NTCA) showed strong force outputs. However, the strain from NTCA was not much enough for practical application. This paper introduces SPX-TCA (STCA) which is fabricated with Spandex fibers. NTCA and STCA were fabricated, and their performances were compared by using the performance evaluation device. STCA showed larger strain, and it was actuated lower temperature than NTCA.
