Abstract |
As wearable electronics becomes more and more a common part of everyday life, the window for portable generators to power these devices increases. Batteries are alone the main source of power, but they have their limitations. The design of an electromagnetic generator that can be integrated within shoe soles is described. In this way, parasitic energy expended by a person when walking can be tapped and used to power portable electronic equipment. Designs are based on discrete permanent magnets and copper wire coils. The overall system of induced generator AC voltage, DC conversion and proposed applications is described. |
