Abstract

In the COVID-19 pandemic, lockdown and acryl partitions were adopted as countermeasures against droplets/aerosol infections; however, these countermeasures restrict communication. In this study, a blocking device was developed using negative ions and an electric field. The device blocks mists simulating droplets/aerosol by a maximum of 89% but transmits light and sound, which is important for communication. The device demonstrated effective blocking performance for aerosol, including the COVID-19 virus spread from patients in a clinic. Our device can help prevent infections without disrupting communication.

摘要

在 COVID-19 大流行期间，封锁和亚克力隔板被用作防止飞沫/气溶胶感染的对策；然而，这些对策限制了交流。在这项研究中，开发了一种使用负离子和电场的阻挡装置。该装置可阻挡模拟飞沫/气溶胶的雾气，最高可达 89%，但可传输光和声音，这对于交流很重要。该装置对气溶胶（包括从诊所患者传播的 COVID-19 病毒）表现出有效的阻挡性能。我们的设备可以在不干扰交流的情况下帮助预防感染。
