With more and more wearable electronics entering the market, the bottleneck of batteries attracts considerable attentions because of its limited lifetime and energy storage capacity. To solve this problem, triboelectric nanogenerators (TENG) have recently been researched to be applied on harvesting mechanical energy from ambient environment, which is of great significance in the field of energy conversion...
We develop PDMS and PMMA triboelectric surfaces with micro/nanopatterning via simple and effective methods, and starting from Si substrates anisotropically etched with low KOH concentration solution. A hierarchical structure formed by micro-pyramidal structures with superficial nano-roughness, is developed in a 200 µm PDMS layer. In parallel, by means of a PDMS stamp and nanoimprinting technology,...
Triboelectric nanogenerator (TEG) as a novel energy harvester has received a great attention since 2011, although the influence of hygroscopicity of triboelectric materials is still lacking. In this paper, we have focused on the effect of hygroscopicity on the output power from the TEG. It was found that under the same mechanical excitation, the output power of the TEG fabricated with hygroscopic...
