Sibionics GS3 - The world's thinnest CGM sensor, with 14-day monitoring
Sibionics GS3 represents the latest generation of continuous glucose monitoring (CGM) sensors from Sibionics, designed to set a new standard for comfort and discretion. With dimensions of just 24.8 × 17.8 × 2.9 mm and a weight of only 1.7 grams, GS3 is the thinnest and lightest CGM sensor in the world - almost imperceptible on skin, even under the lightest clothing.
Designed for people with metabolic health, including children from 3 years old, the GS3 sensor offers 14 days of continuous glucose monitoring, with clinical accuracy MARD of 8.83% and water and dust resistance IP38 - superior to most sensors on the market.
Revolutionary design - integrated all-in-one
Unlike the previous generation (GS1), which had the applicator and sensor as separate pieces, Sibionics GS3 integrates the applicator and sensor into a single compact device. This means:
- Single-step application - no need to assemble separate components; open the package and apply directly to your arm
- Zero risk of assembly error - eliminating the assembly step completely removes the possibility of incorrect application
- Completely painless process - the all-in-one system applies the sensor precisely and uniformly, with a micro-needle that retracts automatically
The sensor is applied to the back of the arm and automatically begins transmitting data to your smartphone via Bluetooth, without manual scanning.
Sibionics GS3 vs. GS1 - what has improved?
GS3 represents a significant evolution over GS1 in all aspects:
| Feature | GS1 | GS3 |
|---|---|---|
| Dimensions | 33.5 × 20 × 5.3 mm | 24.8 × 17.8 × 2.9 mm |
| Weight | 3.84 g | 1.7 g |
| Application | Separate applicator + sensor | Integrated all-in-one |
| Water/dust resistance | IP28 | IP38 |
| Bluetooth range | 6 m | 10 m |
| Minimum age | 3-18 years (variable) | From 3 years |
| Product validity | 12 months | 18 months |
SIBIONICS Application - Complete glucose tracking
The GS3 sensor works with the SIBIONICS application, available free on iOS and Android. The application offers a complete ecosystem for glucose tracking:
- Real-time graphs with glucose values and trend arrows (rising, falling, stable)
- Customizable alerts for low or elevated glucose levels, with the option to Override Do Not Disturb for alerts even in silent mode
- AGP reports (Ambulatory Glucose Profile) - generation, download and sharing with your medicul specialist
- Time in Range statistics - the percentage of time spent in the optimal glucose range
- Detailed history with visualization by hours, days and weeks
- Data sharing - family members or your doctor can monitor your glucose values
The extended Bluetooth range of 10 meters (compared to 6 meters on GS1) allows for a more stable and flexible connection with your phone - you no longer need to keep your smartphone next to you all the time.
Approved for children from 3 years old
Sibionics GS3 is approved for use in children from 3 years old, making it one of the most accessible CGM options for families with children diagnosed with type 1 metabolic health. The extremely small size (almost half that of GS1) and weight of only 1.7 grams ensure maximum comfort on children's sensitive skin, without limiting daily activities - play, sports, bathing.
Combined with the data sharing feature in the SIBIONICS application, parents can monitor their child's glucose in real time, directly on their phone, receiving instant alerts for critical values.

The difference between CGM readings and classic glucometer
The GS3 sensor measures glucose from interstitial fluid (ISF - interstitial fluid), not directly from blood. Between changes in blood glucose and those in interstitial fluid there is a physiological delay of 5-10 minutes. This means that CGM values and those of a classic glucometer will never be identical at a simultaneous measurement - and the difference is normal and expected.
It is recommended to verify with a classic glucometer (finger prick) in situations where the values displayed by the sensor do not match the symptoms felt or before important therapeutic decisions.
Who is Sibionics GS3 recommended for?
- Children with metabolic health from 3 years old - the smallest and lightest sensor, comfortable on children's sensitive skin
- People who prioritize discretion - at 2.9 mm thickness it is invisible under any type of clothing
- Active and athletic users - IP38 and 1.7g weight allow use in any activity without discomfort
- People with metabolic health who want next-generation CGM monitoring at an excellent value for money
- Users migrating from GS1 - all improvements (size, application, Bluetooth, IP) at a comparable price
- Parents - remote monitoring through the application, alerts on the parent's phone, approved from 3 years old
The Sibionics GS3 sensor is available for direct online purchase. It is a CE certified medical device.
Important note: In certain clinical situations, verify values with a classic glucometer, especially when symptoms do not match the values displayed by the sensor.

Frequently Asked Questions
How long does the Sibionics GS3 sensor last?
The GS3 sensor provides 14 days of continuous glucose monitoring. After the 14 days expire, the app will notify you to replace the sensor.
From what age can GS3 be used?
Sibionics GS3 is approved for use from age 3, being one of the few CGM sensors with pediatric approval from such a young age.
What is the difference between GS3 and GS1?
GS3 is smaller (24.8×17.8×2.9mm vs 33.5×20×5.3mm), lighter (1.7g vs 3.84g), has an integrated all-in-one applicator (vs separate), IP38 (vs IP28), Bluetooth range 10m (vs 6m), and shelf life of 18 months (vs 12).
How is the GS3 sensor applied?
GS3 has an all-in-one design - the applicator and sensor are integrated. Open the package and apply directly to the back of your arm in a single step, with no assembly required.
Is it water resistant?
Yes, GS3 has an IP38 rating, providing water and dust resistance. It can be worn while showering, swimming, and during intense sports activities.
How accurate is the GS3 sensor?

What app does GS3 use?
GS3 works with the SIBIONICS app, available free on iOS and Android. It offers real-time graphs, alerts, AGP reports, Time in Range statistics, and data sharing with family or your doctor.
Why do sensor values differ from glucometer readings?
The sensor measures glucose in interstitial fluid (ISF), not directly from blood. There is a physiological lag of 5-10 minutes, which means simultaneous readings will not be identical. This difference is normal.
