The FreeStyle Libre 3 is one of the smallest sensors available, about the size of two stacked coins. A patch made for the Libre 2 would be far too large, so our Libre 3 patches are cut specifically for it (5.3 cm for the round models). They also fit the Libre 3 Plus and the Medtronic Instinct, which share the same sensor.
Because the sensor is so small, centre the opening carefully before pressing the patch down, then smooth it from the sensor outwards. Readings are sent to your phone as usual: the patch does not cover the centre of the sensor.
Pair your patch with a Dia-Style armband for FreeStyle Libre 3, 3 Plus and Instinct. Still on the Libre 2? See our FreeStyle Libre 2 adhesive patches, or browse all Patch Me Up! adhesive patches.
