Outline of Final Research Achievements

In order to make mechanical indexes for evaluating the quality and strength of human bones, sectional modulus of cortical bones against bending moment and muscle at forearm were analyzed through CT (computed tomography) images. The aging characteristics of women aged 50 to 82 were investigated. The ratio of cross section of muscle to bone and the strength index by using natural frequency of forearm bones corresponding to Young’s modulus were calculated. These indexes showed the tendency to decrease with aging similarly to the bone mineral density. Effective arrangement of sensors and bending properties of thin piezoelectric films were investigated and then the usage as an equipment for measuring and revealing the load relationship between bones and muscle was ascertained.
