Is at hand any sensor to detect human skin?
Answers:
For any particular purpose?
Skin can be detected by its conductivity and capacitance, and there are sensors of various types that can detect the electrical characteristics of skin.
See the connection below for an extremely practical use of skin detection devices. The little video clip uses a hot dog in place of a finger, but it is still very impressive. Source(s): http://www.sawstop.com/howitworks/how_mo…
