"triboelectric nanogenerator, the physical energy generated through body movements... rectifier provides negative charge to the body... rate of decrease in body electric potential varies based on voltage, current, and charge triboelectric nanogenerator, and type and surface area of discharger... triboelectric nanogenerator applied to sole of shoe... increase in the electric potential of the body was prevented. This is significantly more efficient than existing wireless antistatic wristbands in the market"
