How can this work? Another interesting point to consider is that in addition to acting like a resistor, the epidermis acts like a capacitor if placed in contact with a piece of metal (the underlying tissue is like one plate of a capacitor and the metal surface is like the other plate - the dry epidermis is the less-conductive material or "dielectric" in between) . It would be even more convincing to get abunch of volunteers, have half of them touch active touch screens, and have half of them touch fakes. [6] Electrical injuries affect more than 30,000 people a year in the United States and result in about 1,000 deaths. What are the different systems present in human body? Under dry conditions, the resistance offered by the human body may be as high as one megaohm. An additional resistance is that of the internal body itself and the length of the transmission path.
