Sensors for IoT

Sensors for IoT to monitor pH and ions in water and soil, food, body fluids, and more.


Together with the Holst Centre, we are developing multi-ion sensors to form the senses of the IoT. They leapfrog the current performance of the state-of-the-art sensors in a mass-producible, wireless, energy optimized and miniaturized package.

Our solution

Imec was the first in the world to demonstrate a solid state miniaturized sensor that simultaneously determines pH and chloride (Cl-) levels in fluid. 

  • Measures pH and Cl-, and allows for additional ion tests such as Na+ and K+ 
  • Stable without calibration for 3 months to 6 months
  • Cost-effective, thanks to SoC (system on chip) integration 
  • Similar or better performance compared to today’s standard single ion measuring equipment 


  • Internet of Things
  • Environmental monitoring
  • Precision agriculture
  • Diagnostics for personalized healthcare
