| Research Abstract |
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.
