What Is the FreeStyle Libre 2 PLUS Sensor?
The FreeStyle Libre 2 PLUS Sensor is a next-generation continuous glucose monitoring (CGM) device designed to provide real-time glucose readings with improved accuracy, extended wear time, and suitability for younger users aged 2 years and above. It builds on the original FreeStyle Libre 2 system while offering an enhanced 15-day wear period and reliable Bluetooth communication.
Approved for use in children as young as 2 years old, this device marks a significant advancement in accessible diabetes management. With automatic glucose updates every minute, customisable alerts, and a 6-metre Bluetooth range, the FreeStyle Libre 2 PLUS Sensor makes glucose monitoring easier, smarter, and more convenient.

How Does the FreeStyle Libre 2 PLUS Sensor Work?
The sensor is applied to the back of the upper arm and uses a thin, flexible filament inserted just beneath the skin to detect glucose levels in the interstitial fluid. It records glucose data every 60 seconds and transmits it via Bluetooth to a compatible smartphone app or reader.
Unlike manual blood glucose tests, the FreeStyle Libre 2 PLUS offers:
- Real-time readings without painful finger pricks.
- Internal storage of up to 8 hours of data, so no information is lost if you are out of range.
- A comprehensive view of glucose trends and patterns throughout the day and night.
This continuous feedback supports better decision-making regarding food intake, activity, insulin doses, and medication adjustments.
For clinical guidance on CGM systems, see the NICE guidelines on diabetes technology.
