The device harnesses both sunlight and mechanical energy.
Nanoscale generators can turn ambient mechanical energy--vibrations, fluid flow, and even biological movement--into a power source. Now researchers have combined a nanogenerator with a solar cell to create an integrated mechanical- and solar-energy-harvesting device. This hybrid generator is the first of its kind and might be used, for instance, to power airplane sensors by capturing sunlight as well as engine vibrations.
