Outline of Final Research Achievements

We have developed flexible TEG modules for applying to heat sources with the curved surface such as exhaust pipes using ICA packaging technology. The module concept is that a mass of small Bi-Te thermoelectric chips are tightly mounted on a thin film substrate and connected with flexible and stretchable ICAs by printing technique. Fabricated TEG modules with 250 p-n pairs of thermoelectric chips have been evaluated in detail.
