Batteries Based on Sweat and Human Blood

U.S. researchers have created a new electric battery, capable of operating on human blood or sweat.  In structure the battery is similar to a simple piece of black paper.  Researchers have produced a molecular structure formed in proportion of 90% of pulp and proportion of 10% of nano-tubes of carbon that plays the role of electrodes and allow the passage of electric current.

The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles.

The battery works at temperatures from 37.8 to 148.9 degrees Celsius and may have a wide range of applications. Robert Linhardt, a member of the team that developed the battery, says “it could be easily implanted directly under the skin.” 

Traditional batteries contain a large number of separate components, while components of paper batteries are integrated into a single structure, which makes them more efficient in terms of energy. Further, the paper battery can be rolled up, folded, rumpled or even cut up into several pieces without losing their properties or technical capacities.
