目的-本文旨在提供一个诊断系统原型，用于检查人类正常移动过程中脚施加到基底上的力的分布。由于传感器的可靠性、用户友好的操作方式和基于廉价部件的设计，所提出的系统与目前可用的其他设备相比具有竞争力。检查结果通过无线电模式传送。它的记录和可视化是可能的个人或移动的computers.Design/方法/途径-在选择的传感器基板，许多聚合物驻极体进行了检查。选择聚偏氟乙烯薄膜，因为它们具有良好的电荷均匀性，可接受的温度范围宽，机械应力和输出信号之间的线性关系和高的抗挤压性。该系统的措施，在film.Findings中产生的电荷-记录的压力相对于最大值，因此，测量系统不需要校准。同时记录的数据从所有八个传感器允许跟踪信号没有distortion.Originality/值-一个阵列的传感器安装在鞋垫。测量装置固定在鞋的外表面上。重量为75 g。传输范围适用于在自然环境中、传统诊室之外的检查。软件专用于分析足部运动的每一时刻的压力分布。该系统适用于扁平足、糖尿病足及创伤后恢复过程的检查。
Purpose - This paper aims to present a prototype of the diagnostic system for the examination of the distribution of the force applied by foot to substrate during usual human moving. Presented system is competitive to other currently available devices, thanks to sensors reliability, user-friendly operation manner and design based on cheap parts. The results of examinations are transmitted by radiomodem. Its recording and visualization are possible on either personal or mobile computers.Design/methodology/approach - During selection of the sensors substrate, many polymeric electrets were examined. Polyvinylidene fluoride films were selected, because they have good charge uniformity across the surface, wide range of acceptable temperatures, linear relation between mechanical stress and output signal and high resistance for squeezing. The system measures the charge generated in film.Findings - The pressures are recorded in relation to maximum value; therefore, measuring system does not require calibration. The simultaneous recording of data from all eight sensors allows tracking the signal without distortion.Originality/value - An array of sensors is installed in the shoe insole. The measuring device is fixed to the outer surface of the shoe. Its weight is 75 g. The range of transmission is suitable for examination in the natural environment, outside traditional consulting room. Software is dedicated for analysis of the pressure distribution in every moment of the foot movement. The system is suitable for examination of flat feet, diabetic foot and recovery progress after injures.
