Ultra-wide-range flexible sensor, preparation method thereof and distributed pressure monitoring system

Abstract

The invention provides an ultra-wide-range flexible sensor, a preparation method thereof and a distributed pressure monitoring system, the ultra-wide-range flexible sensor comprises a first flexible silica gel surface layer, a second flexible silica gel surface layer and a functional interlayer, and the functional interlayer is located between the first flexible silica gel surface layer and the second flexible silica gel surface layer; the functional interlayer is a piezoresistive induction and enhancement structure layer and is used for piezoresistive induction and structure enhancement; andthe first flexible silica gel surface layer and the second flexible silica gel surface layer are made of flexible matrix polymers. The flexible pressure sensor has an ultra-wide measuring range, the effective elastic measuring range reaches 6 MPa, and the limit pressure monitoring value reaches 12.5 MPa. The distributed pressure monitoring system has high monitoring induction density for dense andmulti-point pressure; and the preparation method is simple in process and suitable for large-scale batch production.

[0003] Pressure sensors are used to measure surface forces between contacting surfaces and are widely used in various industrial practices. In recent years, with the research and development of new materials and sensing technologies, pressure sensors with high flexibility have become a development hotspot and can be widely used in wearable electronics, smart clothing, electronic skin, industrial robots, and human health monitoring. and other neighborhoods. To put it simply, the flexible pressure sensor is composed of a conductive pressure-sensitive material and a flexible subs...

AI Technical Summary

Problems solved by technology

At present, the effective ranges of the flexible pressure sensors published in the literature and sold on the market are all within tens or hundreds of kilopascals, and no flexible pressure sensors with a monitoring range of MPa have been found yet.

In addition, the preparation process of the existing flexible pressure sensor is complicated, the cost is high, and the scalability is low.
