Accuracy: Lower MARD values indicate higher accuracy (prioritize models with <10%, and those below 9% are top-tier);
Wearing experience: Weight <4 grams and thickness <3 millimeters provide a more comfortable, almost imperceptible feel; IPX8 waterproofing is suitable for active users;
Long-term cost: Consider whether the transmitter is reusable (a modular design saves thousands of yuan annually compared to an integrated design).
Silicon-Based Dynamic Sensor
Key Features: IPX8 waterproof rating, remains functional after 30 minutes of submersion, ideal for active individuals;
Real-world experience: Fitness coach Wang (Type 1 diabetic) reported that wearing it during running, swimming, and weightlifting was completely fine. The sensor is flexible and won't fall off even with large movements. Data transmission is stable, and it can even cache data in areas without signal coverage;
Suitable for: Diabetics who are active and frequently come into contact with water;
Cautionary Notes:
You must verify the "Class III Medical Device Registration Certificate." Products without this certificate may be of inferior quality and their accuracy cannot be guaranteed.
For sensitive skin, it is recommended to choose flexible adhesive patches and apply a layer of protective cream (available at pharmacies) to the skin before wearing to reduce the risk of allergic reactions.
Do not blindly trust claims such as "lifetime no consumables required" or "100% accuracy." The accuracy of continuous glucose monitors is affected by temperature, humidity, skin condition, etc., and a reasonable margin of error exists.
