MICROSTRUCTURED FLEXIBLE PRESSURE SENSOR AND PREPARATION METHOD THEREFOR

Disclosed in the present invention are a microstructured flexible pressure sensor and a preparation method therefor. The flexible pressure sensor comprises two or more pressure sensing layers, which are arranged in a stacked manner, wherein the pressure sensing layers each comprise a fiber cloth substrate and a nano conductive material, which is deposited on the surface of the fiber cloth substrate. The preparation method comprises the following steps: preparing a nano conductive material dispersion liquid; immersing a fiber cloth substrate in the nano conductive material dispersion liquid, and depositing a nano conductive material on the surface of the fiber cloth substrate by means of an electrodeposition process; and drying the electrodeposited fiber cloth substrate, so as to obtain pressure sensing layers; and stacking and packaging two or more pressure sensing layers and extracting an electrode, so as to obtain a microstructured flexible pressure sensor. The microstructured flexible pressure sensor provi
