Method & Evidence

AimTo develop and evaluate multifunctional origami-structured triboelectric nanogenerators (TENGs) capable of harvesting diverse low-frequency mechanical energies to power self-powered photo-induced oxidation systems for green energy harvesting.

MethodExperimental research and materials science investigation

ProcedureResearchers designed and fabricated zigzag-origami-structured TENGs using composite films of zinc coordination polymer (Zn-CP) and ethylcellulose (EC). They systematically varied the Zn-CP content, scaled up the device dimensions, and integrated multiple units to optimize triboelectric performance. The optimized TENGs were then tested for their ability to harvest energy from human motion and water waves, and this harvested energy was used to power a photo-induced oxidation system for converting aldehydes to carboxylic acids.
