Energy-harvesting rubber could power phones

Talk about the rubber hitting the road. Researchers from Princeton and Caltech have come up with a power-generating rubber material that could harness walking and other movement to charge electronic devices.

The "piezo-rubber chips" are embedded in clear silicone rubber sheets that produce electricity when flexed.
