This paper presents a novel self-powered air disinfection system that uses a nanowire-enhanced localized electric field to inactivate airborne bacteria and viruses. The system is powered by a triboelectric nanogenerator (TENG) that converts mechanical vibrations into electricity. The system achieves >99.99% microbial inactivation within 0.025 seconds at a high airflow rate (2 m/s) with a low pressure drop (<24 Pa). This technology offers a rapid and energy-efficient solution for air disinfection.
