Abstract
A high response speed biological gel artificial muscle (BGAM) with a networked pore structure is proposed. The BGAM is prepared from carboxylated chitosan and sodium carboxymethyl cellulose. For the given parameters including the driving voltage and the size of the BGAM, the response speed of the BGAM in this paper is 15 times faster than the BGAM in the existing research. The best result on the response speed of 0.115 mN/s is obtained, the porosity is 18.5%, the elastic modulus is 2.73 MPa, the specific capacitance is 0.23mF/cm2. This BGAM, prepared by cross-linking natural polymers, is biocompatible and degradable.
