摩擦纳米发电机（TENG）作为一种新型能量收集器最近引起了广泛的研究兴趣，尽管环境对其性能的影响仍然缺乏。本文尝试通过实验量化相对湿度 (RH) 以及压力对 TENG 产生的电荷的影响。研究发现，在相同的机械激励下，当环境压力下相对湿度从90%降低到10%时，TENG产生的电荷增加了20%以上。然而，当空气压力从大气压降低到接近 0% 的 50 Torr 时，产生的电荷减少，而当相对湿度较高时，最佳压力会转向较低水平。这项研究不仅有助于设计和封装在不同环境和极端条件下运行的摩擦起电装置，而且有助于从根本上理解摩擦起电效应的机制。 (C) 2013 Elsevier Ltd. 保留所有权利。
Triboelectric nanogenerator (TENG) as a novel energy harvester has raised wide research interests recently, although the environmental effect on its performance is still lacking. This paper attempted to experimentally quantify the effect of the relative humidity (RH) as well as the pressure on the charge generated from a TENG. It was found that under the same mechanical excitation, the generated charge of the TENG increased more than 20% when RH decreased from 90% to 10% at the ambient pressure. However, the generated charge decreased as the air pressure decreased from atmospheric pressure to 50 Torr at RH close to 0%, while the optimal pressure shifted to a lower level when the relative humidity was higher. This study can contribute not only to the design and packaging of triboelectric devices to operate in varying environments and extreme conditions, but also to the fundamental understanding of the mechanism of triboelectric effect.
