This work, we are the first to discover a high short-circuit current density of triboelectric nanogenerator using recycling rice husks as a source material. On the basis of our FTIR spectra, the nanoporous RHSiO2 fragments offers highly dense Si-O-Si, Si-OH, and OH stretching bonds compare to commercial SiO2 nanoparticles. The RHSiO2 film therefore exhibits strongly tendency to repel the electron because the H atoms have an extremely low electron affinity compared to the PTFE film. The highly positively charged surfaces of the nanoporous RHSiO2 film is five times higher than that of commercially non-porous SiO2 film based on our theoretical calculation results. Rice husk possess many advantageous traits such as their light weight, low cost, being environmentally friendly, high porosity, excellent robustness, exceptionally chemical and thermal stability for superior corrosion resistance, makes it a valuable material for industrial applications. Besides, the active sensor made by lead-free piezoelectric materials and triboelectric materials will also being discussed.
