FreeStyle Libre sensor
The FreeStyle Libre sensor is applied on to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a thin, flexible and sterile fibre is inserted just under the skin. It is held in place with a small adhesive pad. In a study conducted by Abbott Diabetes Care, users agreed that inserting the sensor was no more painful than a typical finger prick test.
