FreeStyle Libre 2 Sensor Teardown

Stap 1

Once you rip off the sticking plaster (you can simply do this with your hand), you can see the front of the sensor from one side. A white cover with the hub for the needle in the center. On the other side, one can already see the board under the transparent plastic layer. Be careful with the needle!

Stap 2

The edge can be ground with a Dremel rotary tool. With the help of some pliers, one can peel off the plastic and with a bit of fine feeling one can take out the board.
