The human body must be constantly supplied with energy in order to maintain all important body functions at all times. Therefore, we are constantly eating and transforming energy from food. However, a large portion of the energy that is supplied is dissipated in heat, which is released by the body and can not otherwise be used in any other way. However, a new invention now wants to utilize this heat energy and can use it to generate relatively simple current.
Researchers at North Carolina State University have developed a wearable in the form of a patch to convert body heat to electricity. The patch can produce about 20 microns of power per centimeter of covered skin area. The first layer of the plaster prevents the body’s heat from escaping unused. Thus the heat travels through a thermo-electronic generator that generates electricity. Before the heat can escape through the last layer again. Nevertheless, the pavement is only two millimeters thick and flexible.
The technology of the patch is part of the “National Science Foundation’s Nanosystems Engineering Research Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies” (ASSIST) and designed for an early commercialization. Initially, instruments such as long-term ECGs are to be measured which permanently measure body functions. However, there is greater potential in technology beyond the health sector. Perhaps we can one day our smartphones alone by our body heat recharge. The research on this project promises to be exciting.
