Researchers from the Korean Advanced Institute of Science and Technology was able to develop an easy and flexible generator powered by body heat.
Today there are two types of thermoelectric generators: one based on organic polymers having a flexible and comfortable to wear on the body and on the basis of inorganic materials. Â They are fficient, but they are bulky and heavy. Â Korean scientists have been able to find a compromise and create a generator characterized by minimal loss of heat energy and maximum power.
The base for this is a thermoelectric-based tissue fiberglass, which printed n-type semiconductors (Bi 2 Te 3) and p-type (Sb 2 Te 3). Â It is quite easy (0.13 grams per square centimeter) and a flexible - the minimum bending radius of the generator is equal to only 20 millimeters, wherein the mechanism is reliable, and does not lose its efficacy even after 120 cycles of bending. Â This generator measures just 10 x 10 inches is capable of producing up to 40 mW of power when the difference in temperature
of the body and the environment around 0.56 ° C.
