In recent years, smart watches and smart rings have become increasingly popular, adorning the wrists and fingers of consumers who use them to monitor their exercise, sleep and heart activity.

Now medical device companies, including Abbott Laboratories, are hoping health enthusiasts will adopt a new kind of wellness accessory: wearable sensors to track glucose levels.

Previous similar devices required a prescription in the US; the new ones don’t, and they’re not just for diabetics.

Abbott’s new device, called Lingo, is aimed at people who don’t have diabetes but want to see how food and activity affect their glucose levels and how that might be connected to their mood, energy levels and quality of life sleep.

Abbott says it’s the next frontier in wearable health technology, though questions remain about whether people will pay for it.
