The second layer of nanogenerators lies just beneath the first and harvests energy from the wind. (sciencemag.org)
The team's newly designed flexible piezoelectric nanogenerator directly stimulated a living rat's heart using electrical energy converted from the small body movements of the rat. (sciencedaily.com)
Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body — its heartbeats, blood flow and other almost imperceptible but constant movements. (sciencedaily.com)
