▎ 摘　　要

NOVELTY - The flexible deformation pressure sensor has a first flexible material layer (1) and a pressure-sensitive layer (2), an electrode layer (3) and a second flexible material layer (4) laminated from bottom to top. The first flexible material layer and the second flexible material layer respectively comprise a flexible material. The pressure-sensitive layer comprises a laser-induced graphene with a regular polygon with a distance. The electrode layer comprises an electrode formed on a substrate material. A flexible material is a material including polydimethylsiloxane (PDMS) and thermoplastic polyurethane (TPU), preferably dimethyl silicone polymer PDMS. The electrode layer is a layer of different materials including Titanium-gold, chrromium-gold and laser induced graphene. USE - Flexible deformation pressure sensor for use in intelligent touch device, surgical sensing tool, biosensor and other research field for measuring dynamic pressure such as pulse or vibration. ADVANTAGE - The pressure sensor includes improved sensing sensitivity, and simplifies the preparation process and period, and optimizes the preparation parameter, so as to realize the optimal sensor performance, and is a preferred method for preparing pressure sensor on a large scale. The resistance change of the pressure sensitive layer is benefited from hexagonal close array interval change and laser induced graphene self-deformation, which greatly improves the sensing sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of flexible deformation pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a flexible deformation pressure sensor. 1First flexible material layer 2Pressure-sensitive layer 3Electrode layer 4Second flexible material layer
