Scientists are genetically engineering viruses in the pursuit of better battery life, perhaps leading to smartphones charged from the motion of walking.
The Department of Energy's Lawrence Berkeley National Laboratory yesterday described a microelectronic device that uses a benign virus to build up electric charge from movement.
Its first prototype was able to display the No. 1 on an LCD display when a person pressed a postage-stamp size button.
That amount of current isn't useful enough to charge common electronics, such as a music player or phone. But the researchers' novel approach to harvesting energy from motion shows … Read more
