The human body is crowded the energy potential, which, according to experts, is used inefficiently. Korean developers decided to use body heat to charge gadgets and created for this purpose a special bracelet.
Glass Fabric – flexible bracelet, developed by the Korea Institute of Science and Technology KAIST. It absorbs the heat of the human body and converts it into electricity. According to the creators of the bracelet, the thermoelectric generator based on light and flexible fiberglass can be used to create the mobile devices on self-supplied.
The device is made by screen printing – thermoelectric semi-n-paste type (Bi2Te3) and p-type (Sb2Te3) applied on the glass fiber. When the bracelet worn on the hand, hundreds of points,inflicted on fiberglass, thickness of several hundred microns, in contact with the body use the heat generated by the skin, to produce electricity. Because the material is very flexible, bracelet well bent and suitable either hand.
Concept can compares, how photovoltaic panels absorb solar energy to produce the electricity. When a temperature difference of 0,6 ° C between the human skin and the ambient air, Glass Fabric can produce about 40 MW of electric power that can be used for charging smart hours or other mobile devices. How inventors hope that, using this technology can charge subsequently and more energy-intensive system.
“Our technology is a lightweight and easy method of making an extremely flexible, lightweight, high-performance generator” – said one of the developers, and stressed that there are plans to introduce this technology in industries such as automotive, industrial, aerospace, shipbuilding, where usually a large amount of heat energy spent wasted. And while Glass Fabric is just a concept.
