In a breakthrough that could free nanomachines from the bulk of batteries, researchers have developed a novel nanogenerator--an array of tiny filaments that converts the smallest motions into electrical current.
The nanowires are crafted from zinc oxide, a safe material that would allow the generator to be used in biomedical applications, and may eventually power nanomotors, tiny sensors, and if in large enough arrays, macroscale devices.
Georgia Institute of Technology engineer Zhong Lin Wang and his colleagues announce the development in the Apr. 6 issue of Science.
The researchers developed the generators with the support of the National Science Foundation, the Defense Advanced Research Projects Agency and the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology.

The research was supported by the NSF Metals Program in the Division of Materials Research through award DMR 9733160.
A prototype nanogenerator was fabricated using an array of zinc oxide nanowires.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
