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 triboelectric nanogenerator (TENG) with an electrocution layer may serve the purpose of filtration and deactivation of SARS-CoV-2. The proposed mask is designed with multilayer filters, in which the inner three layers act as a triboelectric (TE) filter and the outer one as an electrocution layer (EL). The viral particles experience a mildshock in EL due to the electric field produced between the electrocution layers by contact electrification. Four pairs of triboelectric series fabrics, i.e. polyvinylchloride (PVC)-nylon, polypropylene (PP)-polyurethane (PU), latex rubber-PU, polyimide (PI)-nylon are studied to establish the efficacy of the mask. The motional force exerted on triboelectric filter materials can produce sufficient electric power to activate EL. The proposed mask can be used by a wide range of people because of its triboelectric self-powering (harvesting mechanical energy from daily activities, e.g. breathing, talking or other facial movements) functionalities to ensure effective filtration efficiency. More importantly, it is expected to be potentially beneficial to slow down the devastating impact of COVID-19.

在SARS-CoV-2爆发后，在许多国家/地区已强制使用口罩，并且它在对抗大流行中的实用性已被证明是事实。面罩的设计有许多进步，并且本论文描述了一种面罩，其中具有电致死层的简单摩擦电纳米发生器（TENG）可用于过滤和灭活SARS-CoV-2。所提出的掩模设计有多层滤光片，其中内部的三层用作摩擦电（TE）滤光片，外部的三层用作电击穿层（EL）。由于接触带电，电击伤层之间产生的电场使病毒颗粒在EL中发生轻微震动。四对摩擦电系列织物，即聚氯乙烯（PVC）-尼龙，聚丙烯（PP）-聚氨酯（PU），研究了乳胶-PU，聚酰亚胺（PI）-尼龙以建立面膜的功效。施加在摩擦电滤波器材料上的运动力可以产生足够的电能来激活EL。所提出的面罩由于具有摩擦电动自供电功能（可从日常活动中获取机械能，例如呼吸，说话或其他面部动作来获取能量），因此具有广泛的用途，可确保有效的过滤效率。更重要的是，它有望减缓COVID-19的毁灭性影响。所提出的面罩由于具有摩擦电动自供电功能（可从日常活动中获取机械能，例如呼吸，说话或其他面部动作来获取能量），因此具有广泛的用途，可确保有效的过滤效率。更重要的是，它有望减缓COVID-19的毁灭性影响。所提出的面罩由于具有摩擦电动自供电功能（可从日常活动中获取机械能，例如呼吸，说话或其他面部动作来获取能量），因此具有广泛的用途，可确保有效的过滤效率。更重要的是，它有望减缓COVID-19的毁灭性影响。
