- Trace sensor on piece of 4″ Opsite Flexifix (available at Amazon.com)
- Cut out hole
- Apply Dexcom sensor (to arm?)
- Apply Flexifix over sensor adhesive
- Enjoy (hopefully) extended sensor life
For what it’s worth, my first G4 sensor lasted 33 days thanks to this stuff. Not too shabby considering the FDA only approves the G4 for 7.
