Wearable shoulder and back pressure flexible measuring device

Abstract

The invention discloses a wearable shoulder and back pressure flexible measuring device. According to the invention, flexible pressure sensors (12) are arranged in an array manner; a pressure column (9) is arranged above the sensitive area of each flexible pressure sensor; high-density test points can be realized, each test point can work independently, and the device is especially suitable for measuring the shoulder and back pressure distribution on knapsacks, waistbands, shoulder and back correction and other articles so as to test the design rationality of the shoulder and back articles, has the advantages of reasonable layout, good use effect and the like, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a flexible measuring device, in particular to a wearable flexible measuring device for shoulder and back pressure. Background technique [0002] It is known that a flexible pressure sensor refers to a pressure sensor made of flexible materials. The flexible material has the characteristics of softness and easy deformation, and is small in size and has good ductility. It is suitable for backpacks, waist belts, shoulder and back correction, etc. In terms of products, it is used to measure the pressure distribution of the shoulder and back, test the design rationality of such shoulder and back products, real-time data of the force, meet the special requirements for the performance of wearing protective gear, and make the pressure measurement system a reliable measurement tool. [0003] The measurement system requires real-time performance, accuracy, and multi-point acquisition at the same time, and most of the existing pressure te...

AI Technical Summary

Problems solved by technology

[0005] 1. When a large number of dense collection points are required, the piezoresistive pressure sensor test system with an array structure will appear that when an area is under pressure, the resistance value decreases, forming a complex circuit, and it is impossible to accurately and finely display the area. Stress situation

[0006] 2. The current flexible array pressure sensor is basically a plane. The back of the human body and the heavy objects on the back are flexible and elastic. Without hard object support, most of the force will be dispersed and removed after the heavy objects are carried on the back. Significant stress, no good feedback from the system, etc.

[0007] The inventor found through searching that those skilled in the art have not yet proposed a method to solve the above technical problems. Therefore, how to propose a wearable shoulder and back pressure flexible measuring device has become a long-term technical appeal for those skilled in the art.
