Abstract

With the need for clean sustainable energy and low-waste practices rising, battery-free technologies that run on renewable ambient energy sources are an attractive solution to these environmental concerns. Herein, Graphene oxide (GO) and GO-PEDOT: PSS water-based inks were formulated from inexpensive precursor materials following user-friendly, up-scalable methods. GO-based moisture-active films were deposited on flexible lightweight substrates using inkjet printing to fabricate Moisture Energy Generators (MEG), devices that convert ambient moisture energy variation into a voltage output. The performance of the fabricated MEGs was evaluated using a custom-made automated humidity chamber, yielding an average voltage output of V=183 (± 1.76) mV for pure GO and V=194 (± 0.97) mV for GO-PEDOT: PSS, in the relative humidity range of 45-95%. We support that this study may provide fertile ground for the development of low-cost energy harvesters for self-powered portable and wearable technologies, minimising the need for batteries and reducing electronic waste.

摘要

随着对清洁可持续能源和低废物实践的需求不断增加，依靠可再生环境能源运行的无电池技术是解决这些环境问题的一个有吸引力的方案。在此，氧化石墨烯（GO）和GO-PEDOT：PSS水性墨水是采用用户友好、可扩大规模的方法，由廉价的前体材料配制而成。使用喷墨打印将基于GO的湿度活性薄膜沉积在柔性轻质基板上，以制造湿度能量发生器（MEG），即一种将环境湿度能量变化转换为电压输出的装置。使用定制的自动湿度室对制造的MEG的性能进行评估，在45-95%的相对湿度范围内，纯GO的平均电压输出为V = 183（±1.76）mV，GO-PEDOT：PSS的平均电压输出为V = 194（±0.97）mV。我们认为这项研究可能为开发用于自供电便携式和可穿戴技术的低成本能量收集器提供沃土，最大限度地减少对电池的需求并减少电子废物。
