Self-Powered Nanotechnology Closer to Reality
April 8, 2010 | Source: Technology Review
Piezoelectric nanoscale sensors that are self-powered by biomechanical motion (such as body movements) can now produce 2.4 volts, Georgia Tech scientist Zhong Lin Wang reports.
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 — batteries not required.
