多点传感阵列的体压分布测量系统设计

坐姿不良与许多疾病密切相关,而坐姿体压分布不平衡和一些腰椎疾病的发生有着相当大的联系。应用新型导电橡胶为传感材料,利用其力—电阻特性,研制64点阵式压电传感器型坐姿体压分布测量系统。应用本系统对1例正常人,3例患腰椎疾病者进行体压分布测量。实验结果表明:患腰椎疾病者的体压分布不平衡。证明系统的设计方案合理可行,能实现人体与座椅之间压力分布的动态、实时测量。

Design of body pressure measurement system based on multi-point Sensors array

Many diseases are major causes of the sitting posture which are deeply related to the abnormality of the body pressure distribution.A new type of conductive rubber sensor is used to develop a dynamic contact pressure measuring system of body pressure distribution with 64 points.Body pressure is measured through the system in 1 normal individual and 3 who had trauma in lumbar.Eexperimental results show that the body pressure of the people who had trauma in lumbar is not balanceable.Using this system can implement a dynamic,real time measurement for the distribution of pressure between the body and chair.The results indicate that the scheme of the system is reasonable and feasible.
