Never need batteries!


My alumni newsletter reports:

"Research involving U-M has shown that a new energy-capturing knee brace can generate enough electricity from walking to operate devices ranging from a portable GPS locator to an implanted neurotransmitter. The knee brace harvests the energy lost when a human stops the knee after swinging the leg forward to take a step. Researchers hope to improve the device so that it is easy to carry while retaining its energy-capturing capabilities. A lighter brace would benefit hikers and soldiers lacking easy access to electricity and may someday be adapted to power implantable devices such as pacemakers."

Right now, it's just a proof of concept and looks bulky, but this looks interesting.
