摘要

本文通过参数仿真研究了可植入封装热电发生器(TEG)的性能。提出了一种将包装好的TEG嵌入人体组织的有限元模型。在热电堆与周围组织进行热阻匹配后,找到了热电堆提供最大功率的最佳尺寸。模拟了植入体位置及其外壳几何形状对TEG性能的影响。我们发现,在一个很有前景的植入位置,尺寸为20 × 20 mm2的TEG可以在匹配的电阻负载中提供160 μ m{W}$的功率。

Parametric Simulation of a Packaged Thermoelectric Generator for Electrically Active Implants
This work investigates the performance of an implantable packaged thermoelectric generator (TEG) through parametric simulation. A finite element model is proposed, where a packaged TEG is embedded into the human tissue. After thermal resistance matching of the TEG with the surrounding tissue, an optimized size is found for the thermopiles to provide maximum power. The influence of implant position and its housing geometry on TEG performance is simulated. We found that in a promising implant position a TEG of $20 \times 20$ mm2 size can provide $160 \mu \mathrm{W}$ power in a matched resistive load.
