Comprehensive Adhesive Solutions for Continuous Glucose Monitoring (CGM)

Skin-safe adhesives are a vital component in the performance, comfort, and reliability of continuous glucose monitoring systems. Avery Dennison Medical develops adhesive solutions designed to support the unique needs of diabetes care technologies.

Glucose Sensor Patch Requirements for Extended Monitoring

Continuous glucose monitoring (CGM) systems rely on accurate, continuous contact between the glucose sensor patch and the skin. Adhesive performance plays a central role in ensuring the device remains on the body for the full intended wear duration, even through various levels of activity, moisture, or skin sensitivity.

For patients managing diabetes, sensor reliability can directly affect insulin dosing decisions and overall health. A high-quality adhesive for a diabetes sensor patch must offer secure attachment, breathability, skin compatibility, and comfort throughout use.

The secure attachment of a glucose sensor patch is more than a matter of convenience—it directly impacts clinical outcomes. When adhesives fail prematurely, patients may experience gaps in monitoring data that can affect treatment decisions and glycemic control. Our adhesive formulations are designed to provide consistent, dependable performance throughout the entire wear period, supporting better diabetes management.

Unlike medical devices that require only short-term attachment, glucose sensor patches must remain securely in place for up to two weeks. This extended duration presents unique challenges for adhesive technology. Avery Dennison Medical has developed specific formulations that maintain their performance characteristics over time, even as the skin undergoes its natural renewal cycle beneath the device.

Skin Adhesive for CGM: Addressing Unique Patient Challenges

Patients using CGM technologies wear their glucose sensor patches for 7 to 14 days at a time. This extended wear requires adhesives that can maintain bond strength through sweat, showering, and movement; protect against skin irritation and allergic reactions; and accommodate varying skin types, including sensitive diabetic skin.

These requirements are particularly challenging for children, athletes, and patients with active lifestyles. That is why Avery Dennison Medical focuses on developing skin adhesive for CGM solutions that balance performance and comfort for all wearers.

Diabetes can affect skin health in numerous ways, from increased dryness to compromised healing. Our skin adhesive for CGM applications takes these factors into account, with gentle formulations that secure the device without exacerbating underlying skin conditions. This consideration is especially important for patients who must wear sensors continuously for effective disease management.

Daily activities—from showering to exercise—can stress adhesive bonds and potentially compromise device performance. Our glucose sensor patch adhesives are formulated to withstand these challenges while maintaining both comfort and security. The ability to participate fully in daily activities without worrying about sensor detachment improves both compliance and quality of life for diabetes patients.

CGM Tape for Sensitive Skin: Balancing Security and Comfort

Avery Dennison Medical's adhesive platforms are engineered to support long wear on sensitive skin. Our solutions include hypoallergenic adhesives, breathable backings, and repositionable formats that reduce the risk of irritation.

Patients with diabetic skin concerns often experience increased sensitivity due to dryness, neuropathy, or circulation issues. Our CGM tape for sensitive skin is designed to provide gentle adhesion while maintaining sensor security for the full duration of wear.

We offer transparent adhesives for cosmetic discretion, water-resistant coatings for daily use, and skin-friendly formulations tested for biocompatibility. These adhesives help patients maintain lifestyle freedom without compromising device function or comfort.

Children with diabetes present unique challenges for glucose sensor patch design. Their smaller body size, active nature, and developing skin all require special consideration. Our CGM tape for sensitive skin includes options specifically developed for pediatric use, with gentler adhesion profiles and kid-friendly aesthetics that can improve acceptance and compliance.

For continuous monitoring, patients often need to rotate sensor placement to allow skin recovery between applications. Our skin adhesive for CGM systems is designed with this rotation in mind, providing reliable adhesion on fresh application sites while minimizing trauma during removal. This balance supports the long-term skin health of patients who depend on continuous monitoring.

Diabetes Sensor Patch Covers: Extending Wear Time and Performance

Adhesive overlays and patch covers play an essential role in extending the life of glucose monitoring systems. They protect against premature detachment due to environmental exposure and friction.

Avery Dennison Medical offers diabetes sensor patch cover materials that can be customized by size, shape, and wear time. These overlays are designed to improve wear time for the primary CGM sensor patch, available in rolls, pre-cut formats, and custom kits, and compatible with major CGM device brands.

Our materials include options for clear overlays, printed instructions, and moisture-resistant designs to enhance patient confidence and convenience.

Even the best primary adhesives may benefit from additional security in challenging conditions. Our secondary overlay systems for diabetes sensor patch applications provide reinforcement without adding bulk or discomfort. These targeted solutions address edge lifting—a common issue with extended wear devices—while preserving the overall user experience.

The process of applying a glucose sensor patch can affect its ultimate performance and wear time. Our diabetes sensor patch materials are designed with user-friendly features that facilitate proper application, including alignment guides, graduated adhesion, and controlled initial tack. These features help ensure that even patients with dexterity challenges can successfully apply their sensors.

Diabetic Patch Sensor Materials: Advanced Technologies for Adhesion

Each component of a sensor patch, including the primary adhesive layer, interface foam, and overlay, contributes to the device's success. Avery Dennison Medical's platform technologies are used across all these layers to improve the overall experience.

Key features of our CGM adhesive materials include conformability to accommodate skin movement, long wear capability up to 14 days, clean removal with minimal skin trauma, and breathable construction to support moisture vapor transmission. These attributes make our sensor adhesive patch solutions ideal for a variety of skin types and application needs.

The selection of backing materials significantly impacts both the performance and comfort of diabetic patch sensors. Our portfolio includes thin films that move naturally with the body, nonwoven materials that enhance breathability, and specialized composites that balance protection with comfort. This variety allows device manufacturers to select the optimal configuration for their specific monitoring technology.

Avery Dennison Medical continually refines our adhesive formulations to address the evolving needs of glucose sensor patch applications. Recent innovations include improved moisture handling, enhanced biocompatibility, and optimized removal characteristics. These advances support the development of next-generation CGM systems with improved patient acceptance and clinical outcomes.
