Dr. Ville Kaajakari of Louisiana Tech University has developed a technology that harvests power from a small generator embedded in the sole of a shoe. It’s based on new voltage regulation circuit that converts a piezoelectric charge into voltage for charging batteries or powering electronic devices. The shoe power generator is made up of a soft polymer transducer that matches the properties of regular shoe fillings and hence, can replace a standard heel shock absorber. Kaajakari says that the shoe can be used to power RF transponders and GPS receivers.
Earlier this year, PSFK had reported a similar technology – sidewalk panels that harvest pedestrian power to illuminate street lights.
