A Continuous Glucose Monitoring is a small, wearable device that measures glucose levels the day andnight.

Some newer CGM systems combinate the sensor and transmitter into a single unit that communicates directly with a smartphone, eliminating the need for a separate receiver. This design reduces bulk and streaminas the user experience.

The Science Behind Glucose Sensing

Te sensor 's working electrode is coated with glucose oxidase, an enzyme that xidizes glucose to produce gluconic acid hydrogen peroxyde. Te hydrogen peroxyde is then electrochemically decinted, generating a concurt that the transmiter converts into a glucose reading. Because the sensor sits ite thee interstitial fluid - not im thee blood - there a natural physicological delay of about 5 t two 15 minut between blood coche incites and the interstial thele reading.
