New Sensors and Remote Bolus Control
New CGM Sensors
CGM sensors are becoming smaller. The Freestyle Libre 3 was just FDA approved and should be available for patients soon and the Dexcom G7 sensor is expected to follow in the fall.
The Libre 3 is now scan free, collects data 24/7. There is no longer a reader, the data streams directly to an Apple or Android-based smartphone every minute and the readings can be shared to a friend or family member. Detailed reports of the data can be viewed in our clinic and by others through Abbott’s LibreView software.
The sensor was the size of two stacked quarters and is now down to two stacked pennies and is worn on the back of the arm. The applicator is smaller and generates less waste and the system allows the user to set high and low alarms. The sensor warm-up time is one hour, with a 14-day wear length. The cost will be similar to the Libre 2.
The Dexcom G7 is a disposable combo sensor/transmitter that is nickel-sized with a 10-day wear length, and warm-up time of 30-minutes. The 10-day use can also be extended an additional 12-hours to allow for a more convenient sensor change window. The sensor can be worn either on the abdomen or the upper arm.

The Dexcom G7 sensor is expected to integrate with the Tandem Control-IQ and the Omnipod DASH and Omnipod 5 automated insulin delivery systems but there could be a delay after the launch. A smaller, optional receiver will be available and the Dexcom Share feature allows up to 10 other people can follow along in real time.
Finally, the Omnipod 5 automated insulin delivery system is becoming more available for patients who are looking for a tubeless automated pump system and insurance is improving.
It is great to see the continuing evolution of sensors and pump technology as it continues to get smaller and better to improve the user experience for people with diabetes. Hopefully we will see more new products available for use in the next year.
Remote Smartphone Bolusing
People who have the Tandem t:slim X2 pump can now
give a mealtime or correction bolus directly from their
t:connect mobile app on many smartphones. The app
will display glucose the current glucose number from
their Dexcom sensor in the on-screen bolus calculator
and provide the ability to deliver the bolus from the
phone. This eliminates the need to pull out the pump
and will provide more discreet diabetes care and
additional fashion options. There is a limited launch
that requires registration on the Tandem site.
