A photoelectric double response sensor using a structured color hydrogel as conductive electrode was prepared. The structured color hydrogel was prepared by bilayer self-assembly method using dodecyl glyceride itaconate (DGI), sodium dodecyl sulfate (SDS), sodium chloride as raw materials. The photoelectric double response sensor was combined by structured color hydrogel and traditional capacitive sensor.SEM, LCR meter, Tensile testing machine, Fiber optic spectrometer were used to characterize the device structure, optical, electrical and mechanical performance. Results show that in the tensile state (0~100%) and the compressed state (0~60.9 kPa), the capacitance of the sensor changes by 31% and 44% respectively, and the color of the sensor can changes dynamically and reversibly from red to purple in the visible light spectrum. After 15,000 times of cyclic stretching, the performance of the sensor remains stable. By using the stimulus response of sensor's color, the surface of the sensor can clearly shows the location and the shape of the strain source when the sensor is deformed. So the sensor can realize visualization effect during detection.
