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...

Abstract

The invention relates to a high sensitivity flexible pressure sensor and a preparation method thereof; the sensor comprises a conductive silica gel layer and a flexible substrate arranged below the conductive silica gel layer; the flexible substrate is a silica gel layer and in a hollow structure, and arranged in a shape of a Chinese character chuan or jing, or in a rhombus hollow structure; a bonding layer is arranged below the flexible substrate, and made of a hot melt adhesive. The flexible substrate of the flexible pressure sensor is in a hollow structure; the conductive silica gel layer can form bigger deformations when receiving external pressures, and the resistance change is more obvious, so the sensor is more sensitive; different hollow structures can bring about different sensitivities and piezoelectric relations; the hollow structure can be changed so as to adapt to pressure sensors of different occasions; the hot melt adhesive bonding layer can firmly glue the flexible pressure sensor on clothes through hot pressing; the flexible pressure sensor is wearable, hard to drop, and durable.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a high-sensitivity flexible pressure sensor and a preparation method thereof. Background technique [0002] In recent years, wearable electronic devices have developed rapidly and become an important trend in the development of next-generation electronic products. As an important branch of wearable electronic devices, wearable pressure sensors should have a certain degree of mechanical flexibility, fit, high stretchability, high sensitivity, fast response, high durability, etc. Wide application in personal medical treatment, motion detection, human-computer interaction, virtual reality entertainment technology, etc. Existing flexible pressure sensors generally use rubber, which has limited deformation and general sensitivity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-sensitivity flexible pressure sensor and its p...
