"This type of wearable would be very helpful for people with underlying medical conditions to monitor their own health on a regular basis," said Lu Yin, a nanoengineering Ph.D. student at UC San Diego and co-first author of the study published Feb. 15 in Nature Biomedical Engineering. "It would also serve as a great tool for remote patient monitoring, especially during the COVID-19 pandemic when people are minimizing in-person visits to the clinic."

Such a device could benefit individuals managing high blood pressure and diabetes -- individuals who are also at high risk of becoming seriously ill with COVID-19. It could also be used to detect the onset of sepsis, which is characterized by a sudden drop in blood pressure accompanied by a rapid rise in lactate level.
