This paper studies a physical model for reproducing wet sensation. Based on the past studies concerning perception mechanism of wet sensation, we propose and formulate the hypothesis that human feels wet sensation from the combination of increased heat flow between a finger and an object and the variation of contact area of finger. The formulation was verified by experimental results, which measured temperature variation and contact area variation at a contact interface between a finger and a wet surface. Based on the proposed model, we tried to reproduce wet sensation. Although further investigation is required, the result of our pilot experiments showed a potential effectiveness of the proposed model.
