In order to evaluate the quality and strength of human bones, cross sectional areas of bones and muscles of forearm were calculated from computed tomography (CT) image analysis. Then mechanical indexes involving the effect of muscle forces were proposed and the aging porperty was investigated. For comparison the bone mineral density and the strength index by using natural frequency of forearm bones corresponding to Young's modulus were calculated. The proposed indexes with respect to bending and compression showed the tendency to decrease with aging similarly to the bone mineral density and the strength index. Bending and compression properties of thin films of sensors were investigated for revealing the loading relationship between bones and muscle force and measuring those forces, and then the usage as a force sensor was ascertained.

为了评估人体骨骼的质量和强度，通过计算机断层扫描（CT）图像分析计算出前臂骨骼和肌肉的横截面积。然后提出了涉及肌肉力量影响的力学指标并研究了老化性能。为了进行比较，使用与杨氏模量相对应的前臂骨的固有频率计算了骨矿物质密度和强度指数。与骨矿物质密度和强度指数类似，关于弯曲和压缩的拟议指数显示出随着年龄的增长而下降的趋势。研究了传感器薄膜的弯曲和压缩特性，以揭示骨骼和肌肉力之间的载荷关系并测量这些力，然后确定其作为力传感器的用途。
