Nissan replicate human skin feel with leather
Being enveloped in the softness, the warmth, and the texture associated with a pattern of fingerprints is uniquely satisfying to people, who subconsciously interpret these sensations as a gentle caress
Most surfaces of an automobile cabin are experienced through pressure, sliding contact, or both. Nissan have studied both of these interactions as a function of perceived comfort.
Nissan research indicates that the situation of maximum comfort occurs when a leather surface is only slightly less compressible than a human finger pad, and when the roughness of the surface is about that of a human fingerprint. Their overall conclusion is that the texture and yielding nature of baby skin is very nearly ideal.
Nissan is aiming to achieve this using semi-aniline leather with a textured and lightly pigmented protective coating which contains the fingerprint patterns.
