Dr. Ville Kaajakari, assistant professor of electrical engineering at Louisiana Tech University has developed a technology that harvests power from a small generator embedded in the sole of a shoe.
Kaajakari’s innovative technology, developed at Louisiana Tech’s Institute for Micromanufacturing (IfM), is based on new voltage regulation circuits that efficiently convert a piezoelectric charge into usable voltage for charging batteries or for directly powering electronics.

"This technology could benefit, for example, hikers that need emergency location devices or beacons," said Kaajakari. "For more general use, you can use it to power portable devices without wasteful batteries."
