COVID alarm

COVID alarm is a device capable of detecting COVID-19 infection using body odour profile. The novel idea was developed after researchers from London School of Hygiene and Tropical Medicine (LSHTM) and Durham University found that the COVID-19 infection has unique smell due to the changes in the volatile organic compounds that make up the body odour.

These devices, with organic semi-conducting sensors, can be used to conduct fast-paced, non-invasive tests. Their viability in real-world setting is yet to be tested. However, lab testing of these devices revealed that there is very little risk of false positive results.
