FEUD - Field Emission Ultraviolet Device

使用短波长紫外光对表面进行消毒是一种公认的技术，通常用于对医疗设备和无人居住的空间进行消毒。然而，这些光源通常体积庞大，效率低下，含有汞等有毒物质，并且产生的光可能对人眼和皮肤有害。使用低成本，可扩展的材料和工艺，TMD技术公司与布鲁内尔大学伦敦合作，提出开发一种平板远紫外线光源，能够产生对人类无害的波长的光，同时对包括新型冠状病毒（SARS-CoV-2）在内的细菌和病毒有效。该设备将允许在病原体传播风险较高的公共场所广泛安装，有效降低传播速度，有利于国家公共卫生。

The use of short wavelength ultraviolet light to disinfect surfaces is a well-established technique commonly used to sterilise medical equipment and unpopulated spaces. These light sources are however often bulky, inefficient, contain toxic materials such as mercury, and the light generated can be harmful to human eyes and skin.Using low-cost, scalable materials and processes, TMD Technologies, in partnership with Brunel University London, propose to develop a flat-panel far-UVC source capable of generating light at a wavelength proven harmless to humans, while being efficient against bacteria and viruses including the novel coronavirus (SARS-CoV-2). This device will allow widespread installation in public spaces where pathogen transmission is a heightened risk, effectively reducing the rate of spread and benefiting the national public health.
