Continuous glucose monitors (CGMs) are wearable discs placed on the arm that measure glucose in interstitial fluid for two weeks, transmitting data to a phone via NFC.

“So, it's a little disc that you put on the back of your arm. You do it at home. You don't need anybody to put it on for you. And I like to describe it as an easy button because you literally like push it in like a button and then that monitor is there for two full weeks. So you can see your glucose 247 for that two full weeks and it's actually measuring the glucose in your interstatial fluid as opposed to if you're doing a finger prick at home or go to a doctor's office that's measuring blood values. So it's this really flexible microfilament that's measuring just below the surface of the skin.”
