A team of English scientists has developed a corona alarm or sensor that can detect if someone in the room hasCorona Virus In as little as 15 minutes, this technology could provide an affordable way to screen large numbers of people in places including plane cabins, nursing homes, classrooms and offices..
According to a report by the British newspaper “Daily Mail”, the device uses sensors that can detect the distinctive smell that results from chemical changes in the skin or in the breath of people infected with the Corona virus, as the virus causes a change in volatile organic compounds. (VOC) that make up body odor creating a fingerprint that cannot be detected by humans but can be detected by the device when it absorbs the odor.
The device, which can be installed on a wall or ceiling, is programmed to automatically send positive results to the designated person via SMS or email. The hope is that it will be used to detect the virus in places including plane cabins and classrooms and replace the need for widespread testing, although research by the London School of Hygiene and Tropical Medicine and Durham University in its early stages shows the device has an accuracy rate of between 98 and 100% This means that they are much more accurate than lateral flow tests and similar accuracy to PCR tests.

The hardware costs £5,000, and while it’s not cheap, it can reduce the need for testing PCR Frequent and widely lateral flow.
Professor James Logan, chief of disease control at LSHTM , who led the study, said: “These results are really promising and demonstrate the potential for this technology to be used as a rapid, non-invasive test with incredible accuracy.” However, further testing is needed to confirm whether these results can be replicated in real-world settings, if such devices are developed. Successfully for use in public spaces, it can be scaled up easily and affordably, and could protect people from future disease outbreaks, with the ability to develop sensor arrays to detect other diseases within a number of weeks..
The study used body odor samples from socks worn and donated to the team by 54 individuals, 27 asymptomatic or mildly infected individuals, and 27 uninfected individuals. Over two days, the sensors reached accuracy rates of 100 %, but researchers say more large-scale study is needed to determine its effectiveness.
