PAM-SA hydrogel driving membrane with a cross-linked network structure for high stretchability

Abstract

The hydrogel actuated membrane in this paper is highly stretchable while having an electrically responsive output force. At a doping level of 0.6 g SA, the elongation at break of the hydrogel-driven membrane reached 3117% and the output force density reached 16.49 mN/g. In addition, the elastic modulus, tensile strength, and specific capacitance of the driving membrane reached the maximum values of 29.05 kPa, 907.24 kPa, and 452.8 mF/g at SA doping content of 0.75 g.
