Will the user feel the Sensor while wearing it?
The portion of the Sensor that gets inserted under the skin is less than 0.4 millimeter wide (1mm is about the thickness of a few strands of human hair) and it’s inserted only about 5mm under the skin, so most people will not feel the Sensor while it is being worn†.1
†In a study conducted by Abbott Diabetes Care, 94% of patients surveyed (n=122) patients agree that the FreeStyle Libre sensor is comfortable to wear.2
