光コヒーレンストモグラフィを用いた指先皮膚変形計測システムの開発

The sense of touch plays an important role in the evaluation of products. However, there are individual differences in the degree of evaluation and discrimination ability, making tactile sensation difficult to share with others. Therefore, it is necessary to elucidate the factors of individual differences in tactile sensation and to enable quantitative evaluation of tactile sensation. In this study, we focused on the mechanical properties of the stratum corneum of the fingertip as a factor of individual differences in tactile sensation. We constructed a method to measure the thickness and Young's modulus of the stratum corneum. By using optical coherence tomography, we obtain the tomographic images of the fingertip during contact with an object. By preliminary experiments, it was confirmed that the constructed measurement system can be used to measure fingertip skin deformation in response to pressing force and friction force.
