4/04 © MIT-ML Rotary Magnetic Generator Retrofit <strong>Responsive</strong> Environments Group - MIT Media Lab - 1998 • Attaches lever-driven flywheel/generator to shoe - 3 cm deflection, bulky - Suboptimal (e.g., better integration, hydraulics...) • Produces a quarter watt average ( 1 W peak), but very obtrusive! JAP 30
Better Generator Integration Jeff Hayashida’s BS thesis - 1999 • Mechanical generators entirely in insole • Produces about 60 mW average power • Use of a spring to store energy between footfalls can bring a Watt • Mechanically complex and fragile…
