People are able to feel the roughness of the thickness of one millionth of a millimeter

Sensitivity of the human touch porazhaet



Touch - one of the most primitive senses, however, almost every animal relies on it to survive. People seem to have too much more advanced sense of touch than is commonly believed. According to a recent study, people feel uneven thickness of only 13 nanometers - the size of the antibody molecule, or one millionth of a millimeter.

Touch depends on the combination of friction and vibration, with 90% of these people receive information through the face and hands. When you touch a surface, "sensors" in the deep layers of your skin, called Pacinian corpuscles pass you a sense of vibration caused by friction.

To determine the degree of sensitivity, the researchers asked people to touch the 20 different materials - the participants were able to feel your fingers tiny bumps. This means that in the future, nanotechnology could well play a role in tactile perception.
