Dielectric elastomers (DEs) are soft actuation materials with promising applications in robotics and biomedical devices. In this paper, a bio-inspired artificial muscle actuator with artificial tendons is developed for robotic arm applications. The actuator uses a dielectric elastomer as artificial muscle and functionalized carbon fibers as artificial tendons. A VHB 4910 tape is used as the dielectric elastomer and PDMS is used as the bonding material to mechanically connect the carbon fibers to the elastomer. Carbon fibers are highly popular for their high electrical conductivities, mechanical strengths, and bio- compatibilities. After the acid treatments for the functionalization of carbon fibers (500 nm - 10 nm), one end of carbon fibers is spread into the PDMS material, which provides enough bonding strength with other dielectric elastomers, while the other end is connected to a DC power supply. Experimental results show that the conductivity of carbon fibers is capable of transfer input. The bonding strength of carbon fibers and PDMS material is also large enough to pull external load.
