在过去三年中，COVID-19 大流行在全球范围内造成了严重的健康、环境、社会和经济挑战。灭菌是减轻 SARS-CoV-2 等传染性病毒传播的最有效方法之一。然而，极端的灭菌做法可能会在全世界范围内造成严重的健康和环境问题。热、紫外线 C (UVC) 和化学消毒剂需要高能耗，可能会导致健康问题、环境污染和化学品过度使用。在本文中，我们评估了电晕放电（CD）作为一种环保节能的灭菌方法对不同表面进行灭菌的效率。经证实，CD 对于大多数表面和个人防护装备 (PPE) 来说是一种有效的灭菌工艺。 CD 可以减少消毒剂的使用，解决个人防护装备短缺问题，并减少塑料污染和生物废物。 CD 的空气消毒效果为减少空气传播的病原体创造了一种有前景的选择。为了解决CD的安全问题，确认CD的热量、UVC和臭氧排放量处于安全范围内。开发出一种经济实惠的无线 CD 机器人，能够沿着预先设计的路径进行扫描，同时能够避开静态和移动障碍物。自动化 CD 设备和机器人可以成为未来有利的灭菌解决方案，作为一种非接触式、更环保、更高效、更经济、更便携的解决方案。
In the past three years, the COVID-19 pandemic has caused serious health, environmental, societal, and economic challenges globally. Sterilization is one of the most efficient methods to mitigate the spread of infectious viruses like SARS-CoV-2. However, extreme sterilization practices can cause serious health and environmental problems worldwide. Heat, ultraviolet C (UVC), and chemical disinfectants require high energy consumption and can cause health concerns, environmental pollution, and chemical overuse. In this paper, we evaluated the efficiency of corona discharge (CD) as an environmentally and energy-friendly sterilization method on different surfaces for sterilization. It was confirmed that CD is an efficient sterilization process for most surfaces and personal protective equipment (PPE). CD allows for a reduction in disinfectant use, addresses the PPE shortage problem, and reduces plastic pollution and biowaste. The air sterilization effect of CD creates a promising option to reduce airborne pathogens. To address the safety concerns of CD, the heat, UVC, and ozone emissions of CD were confirmed to be within a safe range. A wireless, affordable CD robot was developed with the capability to scan along pre-designed paths while having the capability to avoid static and moving obstacles. Automated CD devices and robots can be favorable sterilization solutions for the future as a contactless, more environmentally friendly, efficient, affordable, and portable solution.
