PTG/e collaborated with a customer from the semiconductor industry on the development of a low-cost, low-energy carbon dioxide (CO2) sensor. Such a sensor type will for example make it possible in the future to measure the CO2 concentration of air with the help of a smartphone.
Our role in the project was to optimise the material used in the sensor, develop a fast screening method based on IR spectroscopy and “print” material onto the sensor chips provided using inkjet printing technology.
Also, a new type of polymer had to be developed for next-generation gas sensors. The PTG/e lab developed a three-component polymer system that was successfully printed onto an electric sensor. The system was deemed so promising that our customer took out a patent on it.
