16. About the Sensor
This section describes the Eversense E3 Sensor and how it is inserted by your healthcare provider.
The Eversense E3 Sensor is a miniaturised fluorometer that uses fluorescent
intensity to measure glucose in interstitial fluid. The sensor is implanted
subcutaneously (under the skin) on the upper arm, leaving no part of the
sensor protruding from the skin. The sensor remains in place and provides
CGM measurements for up to 180 days.
The sensor is encased in a biocompatible material and utilises a unique
fluorescent, glucose indicating polymer. A light emitting diode embedded
in the sensor excites the polymer, and the polymer then rapidly signals
changes in glucose concentration via a change in light output. The
measurement is then relayed to the smart transmitter. Measurements
are completed automatically and require no action by the user.
The sensor is approximately 3.5 mm x 18.3 mm and has a silicone ring that
contains a small amount of dexamethasone acetate, an anti-inflammatory
steroid drug. The dexamethasone acetate minimises inflammatory responses,
very similar to common medical devices, such as pacemakers.
