It is really interesting to know how a blood flow has an influence on tactile sensitivity during Iiurrian fingertip exploration over an environment. In this paper, we examine experimentally how the tactile sensitivity is influenced under the condition that the blood flow is interrupted compulsorily by pressing the base link of humian finger. Through experiments based on Weber's law, we found that the tactile sensitivity improves temporarily with the significance test of 0.1% when pressing a finger base link. Experimental results also show that thete exists a close relationship between the stiffness of fingertip and the tactile sensitivity.
