摘要

小型化的热电发电机,能够将废热转化为几微瓦或毫瓦的电能,似乎对微电子电路的自主供电特别有吸引力,而无需使用电池。然而,迄今为止实现的转换效率非常低。一项批判性的分析表明,在接近理论极限的情况下,仍有一定的改进潜力,但鉴于物理和技术的限制,一些期望似乎值得怀疑。

Energy harvesting using thermoelectric microgenerators: A critical analysis
Miniaturized thermoelectric power generators, which are able to convert waste heat into a few microwatts or milliwatts of electrical energy, seem to be particularly attractive for the autonomous power supply of microelectronic circuitry without the use of batteries. However, the conversion efficiencies achieved so far are very small. A critical analysis shows that there is still a certain potential for improvements toward the theoretical limits, but that some expectations seem questionable in view of the physical and technological limitations.
