Summary
Volatile organic compounds (VOCs) serve as critical early indicators of insulation degradation in high-voltage equipment. However, conventional gas sensors rely on external power supplies, hindering their deployment in distributed or confined grid environments. To overcome this, we propose a self-powered VOC sensor driven by a triboelectric nanogenerator (TENG). The TENG employs an electrospun ethylcellulose composite nanofiber mat doped with bismuth sodium titanate-barium zirconate titanate (NBT-BZT), exhibiting enhanced dielectric properties. By harvesting ambient mechanical energy, the
Read more Read lessTENG generates high-voltage pulses to induce a stable corona discharge within a needle-plate electrode configuration. This localized field preferentially ionizes VOC molecules, yielding measurable variations in output electrical signals. Experimental results demonstrate rapid (<3 minutes), selective, and humidity-resilient detection of representative fault gases (methanol, ethanol, isopropanol, and acetylacetone). Analyte discrimination is achieved based on their distinct ionization energies and diffusion kinetics. This energy-autonomous sensing paradigm provides a maintenance-free, deployable solution for predictive diagnostics and intelligent asset management in next-generation power systems.
