Portable Digital Sanitizer Attached to Smartphones

A South Korean Company has created the UVLEN device, a portable digital sanitizer that is compatible with all smartphones. Using ultraviolet light, which kills bacteria and germs, it can also be used to combat coronavirus on surfaces. Costing at $25, the company claims that the sanitizer is safe for humans and pets, sanitizing one’s hands within ten seconds.

The digital sanitizer annihilates bacteria using ultraviolet (UV) light. Previous studies have shown that UV light can eliminate up to 96% of coronavirus within three seconds and 99% within six. Eric Rondolat, CEO of the lighting company Signify said, ‘We knew that it (UV light) was effective against viruses in general, but we didn’t know if it was the case with COVID-19.’

While exposure to UV rays are harmful to the skin and eyes, according to the World Health Organisation (WHO), short-wavelength ultraviolet light (UVC) is carcinogenic. However, far-UVC light does not harm the skin, and combined with the reflection of other light rays in the electromagnetic spectrum, ‘A thin light diffraction filter converts to light.’
