Embodiment Construction
[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0024] A method for preparing a high-sensitivity flexible pressure sensor, comprising the following steps:
[0025] Step S1, preparing conductive silica gel: uniformly mixing silica gel and conductive components according to a preset ratio to obtain conductive silica gel, and preparing a conductive silica gel layer by using conductive silica gel;
[0026] Step S2, preparing a flexible substrate with a hollow structure on the conductive silicone layer by means of additive printing.
[0027] The flexible substrate in the step S2 is a Chuan-shaped, T-shaped, rhombus-shaped, polygonal or elliptical hollow structure.
[0028] In this embodiment, the flexible substrate in step S2 is a silicone layer.
[0029] It also in...
