Abstract :
Decreasing size and power requirements of wearable microelectronics make it possible to replace batteries with systems that capture energy from the user´s environment. Unobtrusive devices developed at the MIT Media Lab scavenge electricity from the forces exerted on a shoe during walking: a flexible piezoelectric foil stave to harness sole-bending energy and a reinforced PZT dimorph to capture heel-strike energy
