+Erny Cantu Good question! Adding this tech directly to a cellphone unfortunately wouldn’t work because there’s not much mechanical energy in the motion of the cellphone itself, so there wouldn’t be enough to convert to electricity. In order to obtain a watt or so of electrical power, it’s necessary to start with at least as much of mechanical power. The motion of a human body (100 lbs to 200 lbs weight) carries a lot of energy (dozens of watts of mechanical power), so there is more than enough of mechanical energy available to convert to electricity. The motion of a cellphone (less than 1 lb weight) carries a minuscule amount in comparison, so there’s not much energy to convert.
