Wearable energy harvesting devices attract attention as the devices to provide electrical power without inhibiting user mobility and independence. While the piezoelectric materials integrated shoes have been considered as wearable energy harvesting devices for a long time, it is highly expected that they lose their energy harvesting performance after using several times due to their brittleness. In this study, we focused on Fe-Co magnetostrictive materials and fabricated Fe-Co magnetostrictive fiber integrated shoes. We revealed that Fe-Co magnetostrictive fiber integrated shoes provide output power of 341 μW by Villari (inverse magnetostrictive) effect although further quantitative evaluation is required. It seems that the output power is dependent on user habit on ambulation, not on their weight.
