Perceptual sensitivity of the skin depends on skin deformation. Conventionally, perceptual sensitivity and skin deformation are measured independently. So, it is difficult to investigate the direct relationship between skin sensitivity and mechanical properties. In this study, we propose a method to realize simultaneous measurement of skin deformation and sensory sensitivity by applying suction pressure on the skin, which is commonly used for determining the mechanical properties of the skin. We introduced an oscillation of 10 Hz to the suction pressure to generate enough stimuli for the sensitivity measurement. This paper reports an overview of the proposed device and a pressure control method. We also conducted a pilot study to assess the skin deformation and perceptual sensitivity on the forearm skin with 13 subjects. Experimental results showed that the amount of skin deformation had a high correlation with the correct answer rate.
