Nanogenerators produce power from blood stream

With the expansion of a new breed of micro-machines and medical devices that function embedded inside the human body, the researchers focus on finding safe and non-invasive ways of powering this equipment.

The latest breakthrough, in the form of nanogenerators that produce electricity from gushing blood in veins, marks a major advance in this area, writes Fanatical Futurist.

Mimicking the principles of hydroelectric power plants, a team of Chinese scientists has devised this carbon nanotubes device that overcomes the clotting limitations of other miniature energy-harvesting equipment while boosting power conversion efficiency by 20 percent, notes New Atlas.
