PURPOSE: The purpose of this study is to develop new dielectric elastomer (DE) artificial muscle to meet requirements for use as a human assistive device including biocompatibility, achievable stress and strain, and power consumption. METHODS: We develop an artificial muscle structure using DE as a soft actuator to simulate muscle with carbon nanofibers embedded to simulate a tendon structure. A contractile force is generated when an electrical voltage is applied to the DE material through the conductive tendons. The DE material was stretched across a frame and the electrical current applied. RESULTS: Preliminary experimental results show that, when loaded with a 100 gram weight, the DE artificial muscle structure can achieve up to 2% strain output. Power consumption of the DE muscle was less than 100 mW. CONCLUSION: DE artificial muscle has built in sensing and actuation capability and can provide compliant actuation with low power consumption requirements. The DE artificial muscle has significant potential as a human assistive device.
