Imagine being able to swab the inside of your mouth, place it in a device and quickly know whether you’re infected with COVID-19.

The sensor isn’t on the market yet, but soon could revolutionize testing, the researchers say. It could be stationed at the entrances of hospitals, airports and schools, and potentially be put into handheld and even wearable devices.
