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^†.

^†Data on file. In a study conducted by Abbott Diabetes Care, 93.4 % of patients surveyed (n=30) did not feel discomfort under the skin while wearing the Sensor.
