| Outline of Final Research Achievements |
To realize the effective thermoelectric power generation form a small temperature difference encountered in our daily lives, the heat conduction problems for bi-metal plate and wire systems are treated, and the temperature distributions in the systems were able to be controllable. The thermoelectric properties of thin metallic wires were evaluated with use of the fabricated fine-scale thermocouple and the micro-scale potential drop technique, and based on the knowledge, a plate-type thermoelectric power generator was designed. The fabricated thermoelectric power generator realized the sufficient power generation from a small temperature difference, and the maximum power was 0.3uW at the small temperature difference of 40K. It is noted that oxidizing the bi-metal interface and stacking the plate-type thermoelectric power generator were effective to enhance the power generation performance, and the thermoelectric power generator has been expected to drive the various sensors stably.
