And the microstructure, mechanical prope-rties and electrical conductivity of composite hydrogel were studied by infrared spectroscopy (FTIR), electron scanning microscope(SEM), X-ray photoelectron spectroscopy (XPS), universal electronic testing machine and electrochemical workstation. The tensile strength of proposed hydrogel increases with the increase of EG content and the hydrogel conductivity increases first and then decreases with the increase of GO content. The hydrogel maintained good flexibility and conductivity (5.93±0.55) S/m at -20 ℃. Meanwhile, a simple strain transducer was fabricated using the hydrogel can effectively detect the tiny motion of the human body.
