Title:
MICROSTRUCTURED FLEXIBLE PRESSURE SENSOR AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/109639
Kind Code:
A1
Abstract:
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 provided in the present invention uses two or more pressure sensing layers, which are arranged in a stacked manner, such that the sensitivity of the microstructured pressure sensor is improved, and the microstructured pressure sensor has a wider linear range.
