People have been using the mighty energy of water for thousands of years. Using physical principles of operation of hydroelectric power stations, a group of Chinese researchers from Fudan University developed a tiny generator that can be installed inside large human blood vessels and generate electricity from the blood stream.
In 2011, Swiss scientists have already developed tiny turbines, which in theory could be placed inside the veins and produce a small amount of electricity. However, they had a serious drawback: as an artificial obstacle, microturbines could provoke the formation of blood clots.
The development of Chinese scientists is a new type of electrical device that generates electricity by means of an ordered array of carbon nanotubes wrapped around a polymer core. The device was named “fiber-like liquid nano-generator” – FFNG.
While it is unclear how much energy it can produce, however, according to its creators, FFNG will have an energy conversion ratio of about 20%. Scientists have already conducted successful experiments on frogs. In the future, FFNG can become a source of nutrition for implanted medical devices in the human body .
