Abstract
Usage of a face mask has become mandatory in many countries after the outbreak of SARS-CoV-2, and its usefulness in combating the pandemic is a proven fact. There have been many advancements in the design of a face mask and the present treatise describes a face mask in which a simple textile triboelectric nanogenerator (TENG) serves the purpose of filtration of SARS-CoV-2. The proposed mask is designed with multilayer protection sheets, in which the first two layers act as triboelectric (TE) filter and the outer one is a smart filter. The conjugated effect of contact electrification, and electrostatic induction of the proposed smart mask are effective in inactivating the span of virus-ladden aerosols in a bidirectional way. Five pairs of triboseries fabrics i.e. nylon - polyester, cotton - polyester, poly(methyl methacrylate) - PVDF, lylon - PVDF and polypropylene - polyester have been…
