Decreasing size and power requirements of microelectronic devices make it possible to use batteries that are charged by capturing energy from user environment. The parasitic energy expended by a person when walking can be tapped and used to power portable electronic equipments. This paper examines three different devices that can be built in to a shoe. Two of these are piezoelectric in nature and the third is an electromagnetic generator. A flexible piezoelectric foil stave is used to harness sole bending energy and a reinforced PZT multimorph is used to capture heel strike energy. Discrete permanent magnets and copper wire coils were used to harvest energy from movement of legs. The energy scavenged in these ways is stored using two 1.5V NiMH batteries separately.
