I don't know of any that Pete Perkins wouldn't know about.

John referenced “skin resistance.”

To my knowledge, there is no research that shows skin resistance and body resistance as separate parameters.  We only know total body resistance, and that it is a variable that changes – lowers -- with applied voltage and time.

Having said that, a good guess that skin resistance is the predominant parameter at low voltages.  The “body” is comprised of water-predominate organs, so is likely to be a lower resistance than skin resistance and relatively constant with voltage.

We also know that capacitance parallels the total body resistance.  But, as with resistance, we don’t know how to apportion the capacitance to the skin and to the body.

If you know of any such research, please let me know.

Best regards,

Rich

We found very great differences in human  'skin resistance' at effectively zero voltage when designing TV tuners with touch-contact channel selection. We had to make the sensitivity so high that there was a risk that houseflies would change the channel.
