Abstract

The epidemiological information concerning novel corona virus (SARS-Cov-2) seeks attention nowadays to get an overview of global as well as country-based cases and deaths so far. The utilization of face mask has become evident for the protective measure of mankind to filter out the infiltrating virus from outside. In this paper, we have analysed various triboelectric based energy harvester configurations focusing on its application in self-powered smart mask design to combat SARS-Cov-2. Smart mask will comprise of triboelectric nanogenerator (TENG) and a smart layer to execute electrocution of the infiltrating virus as well as ensure the safety of human being (I < 10 mA). The theoretical investigations and simulation studies are carried out for different triboelectric materials and a comparative analysis is also portrayed in the context of designing self-powered smart mask under different operating modes. It has been observed that polypropylene-poly methyl methacrylate (PP-PMMA) material combination produces an electrical field of 0.9916 MV/m which is sufficient to electrocute the virus without causing harm to human body. Hence the design and comprehensive analysis is carried out considering PP-PMMA combination for various possible modes of operation like constant velocity, constant acceleration, sinusoidal and generic one. Here, respiration is considered as major mechanical input source for TENG whereas other biomechanical activities like talking, chewing are also discussed in the context of self-powered application of smart mask. It has been demonstrated that the physiological activity like chewing and respiration altogether produce a typical input force of 23.65 N which is sufficient to electrocute the incoming virus without causing any hazard to human health.

应用于自供电智能面罩的三电能收集器的设计与分析

如今，有关新型电晕病毒（SARS-Cov-2）的流行病学信息引起了人们的关注，以了解迄今为止全球和各国的病例和死亡情况。口罩已成为人类过滤外部渗透病毒的保护措施。在本文中，我们分析了各种基于三光电的能量收集器配置，重点关注其在抗击 SARS-Cov-2 的自供电智能口罩设计中的应用。智能口罩将由三电纳米发电机（TENG）和智能层组成，以对渗透的病毒实施电击，并确保人体安全（I < 10 mA）。针对不同的三电材料进行了理论研究和模拟研究，并在设计不同工作模式下的自供电智能面罩时进行了比较分析。研究发现，聚丙烯-聚甲基丙烯酸甲酯（PP-PMMA）材料组合产生的电场为 0.9916 MV/m，足以电击病毒而不会对人体造成伤害。因此，考虑到 PP-PMMA 组合的各种可能工作模式，如匀速、匀加速、正弦和一般模式，进行了设计和综合分析。在这里，呼吸被视为 TENG 的主要机械输入源，而其他生物力学活动，如说话、咀嚼等，也在智能面罩自供电应用的背景下进行了讨论。研究表明，咀嚼和呼吸等生理活动共产生 23.65 牛的典型输入力，足以电击传入的病毒，而不会对人体健康造成任何危害。
