A team of six Indian-American researchers has developed a new energy-storage device which, besides being paper-thin, can use human blood or sweat to power itself.
The team, led by noted nanotechnologist Pulickel Ajayan of Rensselaer Polytechnic Institute RPI, has developed a battery, which can easily be mistaken for a simple sheet of black paper.
Besides, it is lightweight, ultra thin, completely flexible and geared towards meeting trickiest designs and energy requirements, the INDOlink website said.
8220;More than 90 per cent of the device is made up of cellulose, the same plant cells used in newsprint, loose leaf, lunch bags, and nearly every other type of paper,8221; writer Francis Assisi said. The device can be rolled, twisted, folded or cut into any number of shapes. It even has the ability to function in temperatures up to 300 degrees Fahrenheit and down to 100 below zero, and can be printed like a paper.
8220;It8217;s essentially a regular piece of paper, but it8217;s made in a very intelligent way,8221; Robert Linhardt, co-author of the paper said. The other co-authors include Dr Nalamasu, Victor Pushparaj, Shaijumon Manikoth, A Shavani Kumar and Saravanababu Murugesan.
