Hmmm, interesting. I wonder why they don't use ultrasonic sound instead of a current. It would seem that would scare off many people...Quote from Maverick74:
Body fat analyzers have galvanized electrodes that send a small, painless current of electricity through your body. With the hand-held version, this signal is sent through one hand and travels down to the waist area, back up the body and through the other hand to the other electrode. It measures the subcutaneous fluid under the skin; in other words, your body fat.
