Wearable medical device adhesives

Flexible electronics are moving into a new realm. They are enabling the development of medical monitoring devices that can be worn directly on the skin rather than being strapped on. 

Flexcon® DermaFLEX™ NNRU  skin-friendly wearable device adhesive materials are intended for device attachment to the body such as glucose monitors, insulin pumps, or pulse oximeters.

Comfortable for Patients

The challenge? Finding a substrate that's thin enough to be lightweight, flexible enough to move with the body without pulling, and permeable enough to allow the skin to breath - all while staying adhered for the prescribed period of time without causing irritation.

Benefits

  • DermaFlex™ NNRU disappears on the body in both sight and feel.
  • It's thin and flexible enough to conform to body counters and stretch with movement, but also return to its original dimensions.
  • The adhesive has been tested for biocompatibility by Flexcon's adhesive suppliers using ISO-10993 or similar test methods.
  • The adhesive provides excellent long-term adhesion to human skin.

Rigid Enough for Converting

The challenge for converters is that the films that meet comfort requirements are flimsy, making them very difficult to process because they tend to fold back on themselves like plastic wrap, even when coated with adhesive.


  • DermaFlex™ NNRU is a .001” clear nylon reinforced polyurethane film.
  • It’s much easier to convert than your typical 1 mil PU film because the nylon reinforcement provides enhanced dimensional stability.
  • It’s compatible with EtO and gamma sterilization procedures.
  • The 50 lb. kraft release liner offers a good diecutting base.

Customizable

We can change the DermaFlex™ adhesive, adjust the adhesive coat weight, or swap out the liner to meet the unique specifications of your application.

More Than Medical

This technology isn’t being limited to medical. Wearable devices have the potential to replace personal tracking devices worn as bracelets or necklaces by allowing consumers to wear their devices directly on the skin and out of sight. DermaFlex™ NNRU is rigid enough to convert easily and flexible enough to provide optimum comfort.
