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

  • The standard way of detecting touch as capacitive sensing. This doesn't specifically discriminate between skin and other objects, but there are ways to ignore non-specific contact - e.g. a whole hand or water/dirt over a panel of buttons. Does this meet your needs? You may need to be a bit more specific about what you're trying to achieve.

    Well  I want to know when two animals push against each other to trigger a data point. So the sensor is mounted on the animals chest and I want to know when they mate. Obviously there is a lot hair in the way. Think of a cow or a horse. If it was a pressure sensor it might trigger whilst laying on the ground or rubbing against something.

     

    I can only mount my sensor on the male . Not both animals

     

    Even a combination of pressure and skin detection might reduce error. Plus I don't know if skin detection will work with so much hair.

     

    I know this is quirky but has application in farming

    I think that would work, although there is still the chance of false positives. There are plenty of microcontrollers that do capacitive sensing - you won't even need something as powerful as a SBC. I'm familiar with TI's MSP430 range and there was even a project14 episode on using a MSP430FR2633 dev board as a proximity sensor.

    I'm glad you cleared that up! Otherwise it would have just been weird.
