The development status of our company was also published in the special feature on "Thermoelectric development" development that does not use rare metals.
Thermoelectricconversion modules are used in many applications such as semiconductor manufacturing equipment, PCR inspection equipment, cooling equipment, and consumer products (dryers, etc.). (In cooling applications, they are often called Peltier modules because they use the Peltier effect.)
However, modules on the market use material elements made of bismuth (Bi) or tellurium (Te). These are materials that are considered rare metals. In addition, the fact is that the country of production is biased towards a specific country.
A Thermoelectricconversion module cools one side of the module when a voltage is applied. By connecting something to be cooled to its surface, it cools it, but on the other hand, if there is a temperature difference, it can also generate electricity from it.
In the future, this technology is expected worldwide as a device that generates power by itself instead of an outlet or battery for small power sources such as IoT sensors. Therefore, it is expected that demand will increase. When that happens, it is expected that it will lead to resource problems.
We believe that it is necessary to think about future sustainability because it is a promising technology, and we are thinking about the sustainability of the technology Thermoelectric will support the infrastructure of the future from now on. is challenging.
(Omitted) For Thermoelectric elements that do not use rare metals, Hakusan (Kanazawa City), an electronic parts manufacturer, is also conducting research with the Ishikawa Prefectural Industrial Research Institute. Developed products using easily available magnesium, tin, and silicon as materials. The material cost is expected to be reduced to about one-fourth that of using rare metals. (Omitted below)
