Flexible plantar pressure detection device and shoes

Abstract

The invention relates to a flexible plantar pressure detection device and shoes. The device comprises a flexible substrate layer, a functional layer, a flexible packaging layer and a processing module. The functional layer is arranged on the flexible substrate layer and comprises a plurality of flexible piezoresistive sensing units, a plurality of flexible piezoelectric sensing units and extensible wires for connecting the plurality of flexible piezoresistive sensing units and the plurality of flexible piezoelectric sensing units to the processing module; the flexible packaging layer is located above the functional layer and packages the functional layer together with the flexible substrate layer; and the processing module is used for collecting signals of the multiple flexible piezoresistive sensing units and the multiple flexible piezoelectric sensing units to obtain multiple piezoresistive signals and multiple piezoelectric signals so as to obtain plantar stress data according to the multiple piezoresistive signals and the multiple piezoelectric signals. The device has the characteristic of a piezoresistive and piezoelectric double-measurement mechanism, and is low in cost, longin service life, wide in measurement range, high in sensitivity, and capable of collecting the signals anytime and anywhere without being limited by different external environments, human body movement ranges and human body sole structures.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent insoles, in particular to a flexible plantar pressure detection device and shoes. Background technique [0002] The foot is the only part that is in contact with the ground in normal human activities. With different physiological activities, the pressure felt by various parts of the sole of the foot is also different. Therefore, the plantar pressure has become a key feature in human daily life. Gait analysis generally refers to the study of human action and movement. By studying the law of human movement, it reveals the change of gait law when the human body is abnormal. The collection and detection of plantar pressure signals is of great significance to the analysis of different gait characteristics, motion states and physiological parameters of the human body. [0003] In related technologies, the existing plantar pressure measurement systems are mainly divided into three categorie...
