Thermoelectric generators for mobile communication systems

Thermoelectric generators are devices which accomplish the direct conversion of heat into electricity. Although the thermoelectric effect has been known for more than a hundred years, it was not until the late 1940´s with the advent of semiconductor technology that the use of this effect as a practical means of generating electrical power could be foreseen. Today, thermoelectric generators are reliable, economical, off-the-shelf power supplies available to fill a wide variety of needs. These devices are playing an increasing role in the field of mobile communications.
