PRIGEL – 3D Cellulose Hydrogel for Patches

Beneli AB, Rise, Sweden

Beneli develops new, printable interactive gels for use in body-fixed monitoring equipment for the detection of cardiovascular activity.The detection and transportation of signals between skin and patch is managed through the 3D-printed conducting polymer and cellulose fibers based electrodes, which also is the structure that creates the gel-network. This demonstrator is used as a replacement for the current commercial hydrogel and tested and compared in the current test environment.


  • To fine tune the adhesive properties of the hydrogel both to the skin and to the electrode
  • To reconstruct polymers and create a bio-based alternatives that improves cost, shelf live and performance
  • To simplify manufacture

Target Group

  • Healthcare
  • Consumer Electronics


  • The developed cellulose-based hydrogel showed very low impedance, more than 10 times lower than the fossil-based hydrogels on the market today
  • Cellulose-based fibers are versatile and can be applied to other applications
  • Brings both ionic and electronic conductivity
  • No water leakage during handling
  • Use additive manufacturing which leads to no waste
  • Contributes to a bio-based society by using modified cellulose-based
