Preparation of resistance/capacitance dual-response MXene-based hydrogel flexible sensor

The invention relates to preparation of a resistance/capacitance dual-response MXene-based hydrogel flexible sensor. According to the preparation method, hydrogel with a microstructure is prepared from polyacrylamide, gelatin and MXene, and the hydrogel flexible sensor prepared by combining the hydrogel with an interdigital electrode can detect a resistance response signal and a capacitance response signal at the same time. According to the flexible sensor, the single response signal mode of the flexible sensor can be widened through the detected resistance and capacitance signals and by means of data complementation between the two response signals, mutual calibration of the same group of data is achieved, and the detection precision of the flexible sensor is improved. The MXene-based hydrogel flexible sensor is applied to detection of human body biological signals, such as carotid artery pulse detection and radial artery pulse detection. 电阻/电容双响应的MXene基水凝胶柔性传感器制备，本发明通过聚丙烯酰胺、明胶和MXene制备具有微结构的水凝胶结合叉指电极制备出的水凝胶柔
