Piezoelectric Nanowires Could Power Future Gadgets Using Blood Flow [Nanotech]

Did that headline get your blood pumping? Good. In the future you'll make a great battery.

This is because, in the future, scientists seem to think that piezoelectric nanowires could find a nice home inside our blood vessels. There, they'd use the energy created by blood flow to power our gadgets, pacemakers, or any number of other people-powered devices future inventors can think up. That sounds great in theory, but I assume that, like with most things I put in my body today that sound great and feel good, it will probably cause cancer or something.

Regardless, the scientists want to let us know there are no practical or commercial uses planned for these zinc oxide nanowires. Not for a long while anyway. This means you can stop digging around for that vein now. Oh, that's for the heroin? Nevermind then. [Live Science via Engadget]
