 Hari     Kay     Bingjie Reid  Martin

Under the advisement of Parameswar Hari, Associate Professor of Physics and Engineering Physics, Team Echocharge members Martin Green, Bingjie Ji, Reid Johnston and Katherine Sind developed a nanostructured device for extending cell phone battery life. Through nanotechnology, the group harnessed energy from the voice of the phone user and surrounding noise vibrations. The energy is recycled back to the cell phone battery, increasing its capacity up to 20 percent. The team was awarded $20,000 for its first place win.
