Desired outcome

We look for solutions or technologies that minimize the problems of current water quality sensors. We are interested in single and/or multiparameter sensors. We are especially interested in solutions based on semiconductor sensing and miniaturization technologies, but open to any other kind of technologies or solutions.

Details of the Innovation Need

pH, ORP, conductivity, turbidity and free chlorine are essential parameters to control the quality of recreational water. Currently the type of sensors that are used are quite expensive due to their manufacturing process. In some of this type of sensor, the voltage produced between the internal electrode and the reference electrode is proportional to the values ​​of said parameters present in the analyzed water.

Those sensors are widely used in recreational water installations, but they have the following known drawbacks:

- have a limited shelf life (months): we expect at least 36 months of service life without probems

- require constant maintenance (wintering, calibration and cleaning): we expect to reduce maitenance interventions to 1 per year or less

- are affected by external disturbances: we expect that electromagnetical noise do not affect the signal. We also expect high tolerance to chemicals compounds and flow variation.


- Its large size makes it difficult to integrate into other products. We are looking for a "small size" solutions to facilitate its integration in different products with not to much space available.


- They are expensive. The cost varies depending on what you are measuring and the type of sensor (ex. turbidity is quite more expensice than pH). We expect solution more cost effective compared to actual solution we are using.

We are looking for solutions or technologies that minimize the problems of current sensors. We are interested in single and multiparameter sensors. We are especially interested in solutions based on semiconductor sensing and miniaturization technologies.

The operating requirements are the following:
