Scientists develop stamp-sized, wearable device that can record body temperature and blood oxygen levels to monitor Covid-19

WASHINGTON: Researchers have developed a stamp-sized device, comprising a suite of sensors, including ones , an advance that can be used to catch early signs and symptoms of COVID-19, and help monitor patients as the illness progresses.

The scientists, including John A. Rogers from Northwestern University in the US, said they have tested the novel device on more than 50 physicians, rehabilitation specialists, and patients at the country’s Shirley Ryan AbilityLab and at the Northwestern Memorial Hospital.

According to an editorial, published in the journal Science Advances, the sticker-like medical device, which is of the size of a postage stamp, is soft, flexible, and sits just below the suprasternal notch – the visible dip at the base of the throat.
