ARTICLE #2 FOR IMMEDIATE RELEASE

Nano-sized generator gets big power boost
Nano Letters

The notion of generating electricity from flowing blood, pulsating blood vessels, or a beating heart may seem like science fiction. But scientists are reporting a stride in that direction in the August 8 issue of ACS Nano Letters, a monthly journal, with development a more powerful nanogenerator for powering implantable biomedical devices and other small electronics.

In the report, Zhong Lin Wang and colleagues explain that such nano-devices show great promise for biosensing, environmental monitoring and personal electronics. Lacking, however, are practical ways to power these devices. The report discusses a prototype nanogenerator, developed earlier, which consists of zinc oxide nanowires and could turn mechanical energy into electricity.

Researchers now describe an improved version of the device, which produces 20-30 times more electric current and is able to generate electricity while immersed in biological fluids or other liquids, using ultrasonic waves as the energy source. It sets a solid foundation for self-powering impl
