Health and fitness is a field where sensors will have a huge impact. One part of the potential lies in miniaturisation and price, the other in the awareness we all gain through new technology (fitness watches, smartphones, etc.) and education on body functionality.

Cells use oxygen and glucose to produce energy, and they release CO2 into the bloodstream to be carried to the lungs. The amount of exhaled CO2 depends on the adequacy of circulation in the lungs, which provides clues about circulation to the rest of the body.


When it comes to fitness, your tolerance to CO2 can be improved and you can thereby increase your capacity. One way to improve your tolerance is with a training mask.

But where does the sensor come in, you wonder? Today, CO2 is measured in VO2 tests, a rather complicated test where you have to use fixed equipment in a “lab situation”. We see other ways to do this: in conjunction with training masks and a small mobile sensor that will follow you during your exercise.
