Flexible sensor array

Abstract

The invention discloses a flexible sensor array which is sequentially provided with a first electrode array substrate, an insulating glue layer, a composite pressure-sensitive layer and a second electrode array substrate, and is characterized in that the first electrode array substrate and the second electrode array substrate respectively form a first electrode array and a second electrode array by arranging electrode arrays on a flexible substrate; any point electrode of the first electrode array and one point electrode of the second electrode array are in one-to-one correspondence to form anelectrode group. According to the invention, a large-area sensor array can be realized, the pressure-sensitive array and the electrode array have better connectivity and better adhesive force, the size is smaller, the preparation efficiency is higher, and the repeated installation process of the pressure-sensitive layer is avoided.

Description

technical field [0001] The invention relates to the technical field of flexible sensors, in particular to a flexible sensor array. Background technique [0002] With the improvement of technology and modernization level, people have higher and higher requirements for pressure monitoring. It is not limited to pressure monitoring on regular rigid surfaces, and there are also various forms. Ordinary rigid sensors can no longer meet people's actual needs. For example, people hope to realize real-time monitoring of physiological indicators such as heartbeat, pulse, blood pressure, respiration, etc. through wearable, stickable or even implantable methods. In addition to taking into account accuracy and safety, these products must also take into account the human body. Comfortable to wear, it can withstand various daily movements of the human body, even heavy-duty sports without affecting the performance indicators of the sensor. Due to its random bending or even folding, small si...

Problems solved by technology

[0003] Although flexible pressure sensor technology has been greatly developed in recent years, there are few studies on large-area flexible array sensors.

In large-area integrated applications, the existing sensor based on the coating process generally prepares the pressure-sensitive layer first, and then cuts and installs it according to the application requirements. The material utilization rate is low, the thickness is too large, and the cost is too high

Secondly, the efficiency is too low, and large-area integration is only repeated installation and production of a single sensor, which is not suitable for the production of large-area high-density flexible array sensors.
