摘　　要：医学研究表明 ,人体足部的病态与许多疾病密切相关 ,而足底压力分布的不正常与足部病态有着相当的联系。本研究应用新型导电橡胶为传感器材料 ,利用其力 -电阻特性 ,研制成功了 2 5 1点阵接触力传感型人体足底压力分布的测量系统 ,它包括多点导电橡胶传感器 ,接口电路 ,计算机数据采集和处理系统等。该系统能够实现动态、全场、实时测量 ,并给出直观、功能全面的图像结果显示。文中叙述了系统的设计和工作原理以及临床测试 ,同时给出了它在医学预诊上的应用。It has been shown from medical researches that many diseases are major causes of foot morbidity, which are deeply related to the abnormality of the plantar pressure distribution. In this respect, we made a new type of conductive rubber sensor and designed a dynamic contact pressure measuring system of plantar-pressure distribution with 251 testing points successfully. It includes the muhipoint conductive rubber sensor, the interface circuit and the computer data collecting and progressing system. The measuring system can give the intuitional and full-scale image results with the full-court, real time testing. Also in this paper are introduced the design of the system ,the testing results, and its applications in primary medical studies.
