What is thermoelectric Energy Harvesting?
It's the use of heat or cold sources to supply electrical appliances with energy.
The so-called Seebeck effect is used to generate energy from temperature differences. In this case, an electric current flows between two contact points of two electrical conductors, which have a different temperature. Since the voltages generated by the Seebeck effect are extremely small (a few microvolts per degree of temperature difference), Fraunhofer IIS has been researching for several years to use very small voltages and energy quantities through electrical circuitry and to reduce the energy requirements of electrical systems. Our current developments can already be operated permanently with 2 degrees Kelvin.
