Plantar pressure distribution detection system and manufacturing method thereof

Abstract

The invention discloses a plantar pressure distribution detection system which comprises a detection layer and a processing sending module, wherein the detection layer is configured to detect plantar pressure signals and converts the detected plantar pressure signals into electric signals; the processing sending module is configured to receive the electric signals converted by the detection layer, process the received electric signals and send the processed electric signals to an external receiving device. The invention further discloses a manufacturing method of the plantar pressure distribution detection system. According to the plantar pressure distribution detection system and the manufacturing method of the plantar pressure distribution detection system, a piezoelectric electret used by the system and the method has the advantages of being light, thin and soft, the piezoelectric response is large, the linearity is high, influences of temperature changes within the work temperature range are small, influences of shearing force are small, no influence of bending exits, and thus the plantar pressure distribution detection system and the manufacturing method of the plantar pressure distribution detection system are suitable for real-time detection of plantar pressure distribution.

Description

technical field [0001] The invention relates to a plantar pressure distribution detection system and a manufacturing method thereof, which can detect the plantar pressure distribution of a human body in real time. Background technique [0002] The study of plantar pressure distribution is widely used in various fields, such as biomechanics, clinical medicine, rehabilitation engineering, orthopedics, orthopedics, sports training, shoemaking and many other fields, which has important scientific significance and application value. In recent years, the plantar pressure distribution detection technology has developed rapidly, and dozens of detection systems have appeared so far. The detection techniques used by these detection systems are different, and their performances have their own advantages, which can be roughly divided into four categories: [0003] 1. Footprints. A mat made of resilient rubber or foam with a smooth upper surface and a lower surface with ridges that are...

AI Technical Summary

Problems solved by technology

[0006] However, among the several existing plantar pressure distribution detection technologies, the "footprint" method is too primitive, and the detected data is single, so it is rarely used; "direct visualization technology" uses optical technology to detect the material caused by plantar pressure. Deformation, complex system structure and high cost; the "force plate and load unit" method uses resistance strain gauges and bridge circuits, and the structure is also complicated

In addition, these three methods usually fix the detection system on the ground, and the subjects walk on the surface of the system barefoot or wearing shoes, so the places of use are limited
