Spatial and temporal plantar pressure distributions are important and useful measures in footwear evaluation, athletic training, clinical gait analysis, and pathology foot diagnosis. However, present plantar pressure measurement and analysis systems are more or less uncomfortable to wear and expensive. This paper presents an in-shoe plantar pressure measurement and analysis system based on a textile fabric sensor array, which is soft, light, and has a high-pressure sensitivity and a long service life. The sensors are connected with a soft polymeric board through conductive yarns and integrated into an insole. A stable data acquisition system interfaces with the insole, wirelessly transmits the acquired data to remote receiver through Bluetooth path. Three configuration modes are incorporated to gain connection with desktop, laptop, or smart phone, which can be configured to comfortably work in research laboratories, clinics, sport ground, and other outdoor environments. A real-time display and analysis software is presented to calculate parameters such as mean pressure, peak pressure, center of pressure (COP), and shift speed of COP. Experimental results show that this system has stable performance in both static and dynamic measurements.
空间和时间足底压力分布是鞋类评估、运动训练、临床步态分析和足部病理学诊断中的重要且有用的测量指标。然而，目前的足底压力测量和分析系统穿戴起来或多或少都不太舒适且价格昂贵。本文提出了一种基于纺织织物传感器阵列的鞋内足底压力测量和分析系统，该系统柔软、轻便，具有高压敏性和长使用寿命。传感器通过导电纱线与柔软的聚合物板相连，并集成到鞋垫中。一个稳定的数据采集系统与鞋垫接口，通过蓝牙路径将采集到的数据无线传输到远程接收器。该系统包含三种配置模式，可与台式电脑、笔记本电脑或智能手机连接，能够配置为在研究实验室、诊所、运动场及其他户外环境中舒适地工作。还提供了一个实时显示和分析软件，用于计算平均压力、峰值压力、压力中心（COP）和COP移动速度等参数。实验结果表明，该系统在静态和动态测量中均具有稳定的性能。
