You may soon be able to buy a sticky patch that can help you improve your fitness by monitoring your blood glucose, ketones, lactate and alcohol levels through a small probe placed under your skin. Abbott Lingo is a series of consumer ‘biowearables’ announced at CES 2022, and will use the technology originally developed to help people with diabetes manage their condition.

Abbott made its name with the FreeStyle Libre – a continuous blood glucose monitor consisting of an adhesive patch that is placed on your arm, which contains a sensor that sits under your skin. It measures glucose in the interstitial fluid between cells, reducing the need for finger-prick tests. You can check your glucose level at any time on your phone, and set a custom alarm if it goes too high or goes too low.


The company then moved into sports tech with the Abbott Libre Sense Glucose Sport Biosensor. It works in the same way, but unlike the FreeStyle Libre, it is not a medical device, and is instead intended to help athletes without diabetes understand how their body uses glucose during exercise so that they can adjust accordingly. Prepare your refueling plan.

You can view data from Libre Sense in real time on your smartphone, or use the SuperSense app to sync it with your Garmin Watch, TrainingPeaks or Apple Health.

speaking your language

Lingo sensors (so named because they “speak your body language”) go a step further, monitoring not only blood glucose, but ketones, lactate, and alcohol. They will not be medical devices and are instead intended to guide you toward healthier lifestyle choices.

Ketones are substances produced by your liver when it breaks down fat for energy rather than using carbohydrates, and measuring them will be helpful for anyone trying to lose weight with a ketogenic diet.

Lactate is produced during exercise, and Abbott says tracking it will allow athletes to measure buildup during exercise and improve recovery time.

Ultimately, tracking blood alcohol will allow you to make better decisions, and the company’s CEO, Robert Ford, suggests that it may one day be tied directly to your car’s computer system and help you if your alcohol level is too high. The engine may prevent starting.

The Lingo Sensors are still in development, and there’s no suggested price or release date yet, but we’ll be following Abbott’s progress over the coming months and years, and will keep you updated when we learn more.
