Researchers claimed that a smart ring that constantly measures the wearer’s temperature could help determine whether the person was developing Covid-19, even if the symptoms were very subtle.

According to the details, experts from the University of California and MIT Lincoln Lab studied data on 50 people who owned sensor rings and had had Covid-19 before the study.

The researchers found that temperature data from the ring could reliably be used to detect the early onset of fever – a leading symptom of Covid-19 and the flu.
