The data set comprises skin physiological data recorded at the fingertip, friction data for 12 different samples, and perceptional data with respect to touch of these samples for 60 participants. The study is described in a manuscript titled “Skin factors in tactile friction and perception of materials: hydration, deformability, and age” which is currently under consideration for publication.
