摘要

This paper focuses on the sizing optimization of a thermoelectric generator, combined with a potential heatsink, that harvests heat from the human body. To ensure success, energy models describing a thermoelectric module and a heatsink are introduced; these two models are then simplified for small temperature differences while respecting the continuity between them (both with and without the heatsink). In order to maximize the power produced by such a system, the dual thermal and electrical matching of the generator with its environment is studied in detail. Lastly, to optimize the sizing, a set of optimization parameters are defined, namely leg length, the capture surface area of the thermoelectric generator and, if a heatsink is present, its height. The results derived help draw a conclusion on the pertinence of adding a heatsink, for the purpose of maximizing electrical power while minimizing total volume.
