Moisture sensor in superabsorbing wound dressing

Purpose and goal

The purpose of the project was to develop a wound dressing with an integrated moisture sensor which indicates when the dressing starts to get saturated and can be a decision tool when to change dressing. The goal was to develop the dressing with the moisture sensor and to perform an initial patient study. Both project goals have been achieved.

Expected results and effects

Results from the clinical trial shows that the concept has the opportunity to work and if the function is good, the idea is well received. To show the effects, more data from clinical use of the final product is required.

Planned approach and implementation

The project developed a moisture sensor of printed electronics at RISE and Printed Electronics Arena in Norrköping. After several different lab tests and production of sensors in pilot scale, approval was given to test the moisture sensor on an existing superabsorbent dressing in a small clinical trial. The clinical trial provided more insight into the product´s function. Subsequently, the design of the dressing has been modified for better function together with the moisture sensor.
