素肌の感触評価のための触感センサ

抄録

Humans judge their own skin condition through the tactile sensation experienced in sliding the fingers over their skins. However, there has been no quantitative evaluation method of tactile sensation of bare skin with the same accuracy as that of a professional evaluator. Therefore, we developed a sensor that could evaluate the tactile sensation of skin using the vibrations and friction generated as a motor-driven probe lightly slid over the skin’s surface. In order to verify whether the developed sensor could accurately evaluate tactile sensation, we performed a skin texture measurement test and created statistical models that estimate the palpation scores of a professional evaluator. The physical quantity used for the estimated model was only vibration, but the estimation accuracy was close to that of the model constructed from skin condition indices measured by several commercially available sensors. The developed sensor can be used for evaluating the tactile sensation of bare skin.
