Troy, N.Y. â€“ Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper.
The nano engineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrowâ€™s gadgets, implantable medical equipment, and transportation vehicles.
Along with its ability to function in temperatures up to 300 degrees Fahrenheit and down to 100 below zero, the device is completely integrated and can be printed like paper. The device is also unique in that it can function as both a high-energy battery and a high-power super capacitor, which are generally separate components in most electrical systems. Another key feature is the capability to use human blood or sweat to help power the battery.
Details of the project are outlined in the paper â€œFlexible Energy Storage Devices Based on Nanocomposite Paperâ€ published Aug. 13 in the Proceedings of the National Academy of Sciences.
