Self-Powered Nanotechnology Closer to Reality
Abstract:
This Tuesday at the Materials Research Society spring meeting in San Francisco I sat down with Zhong Lin Wang, director of the center for nanostructure characterization at Georgia Tech. We featured Wang's work on self-powered nanosensors in our "10 Emerging Technologies" issue last year. The payoff from this concept would be huge: nanoscale sensors are exquisitely sensitive, very frugal with power, and, of course, tiny. They could be useful for detecting molecular signs of disease in the blood, minute amounts of poisonous gases in the air, and trace contaminants in food. Eliminating the batteries needed to drive these devices would make it possible to fully miniaturize them.
