These boots are made for walking ... and for powering up your cell phone? It could happen, according to a team of Princeton and Caltech scientists. They report that they have developed an innovative rubber chip that has the ability to harvest energy from motions such as walking, running, and breathing and convert it into a power source.

The features on computer chips are getting so small that soon the process used to make them, which has hardly changed in the last 50 years, won't work anymore. One of the alternatives that academic researchers have been exploring is to create tiny circuits using molecules that automatically arrange themselves into useful patterns.
