Sensing Skin is present

hasher

Hi guys

 

I am working on a project that  involves detection of skin (and hair). The sensor should be in such a way that it should differentiate human skin from other objects like wood,dirt . Is there a commercial sensor on the market that does this ?

 

 

Thanks Paul

  • Capacitive sensing is a good way to go.  I have used multiple capactive sensors in an array to detect proper (full) contact with skin in a medical product.  The idea was to require multiple contact points to verify a verified contact.  If the fur does get in the way (which should not be too much of a problem), you could augment the detection with an I/R sensor to provide an added component of heat to the equation to assist in eliminating false/casual contact.
