Irig’s electronic nose is now even more discerning

Irig’s electronic nose, which was transferred to startup Aryballe Technologies, now has an even broader range of uses. But first it will have to be usable in the field and at wider temperature ranges. Researchers at Irig redid some of the basic science on the device, comparing theory with lab testing results.

They looked at the influence of the emission source wavelength on the system’s sensitivity. They also probed the impact of the thickness and roughness of the metal layers where the biosensors that capture odor molecules are housed. Finally, they came up with a method for characterizing the optical performance of the prism at the heart of the electronic nose. Their results will be used in a PhD research project to design a temperature calibration method suitable for measurements in the field.
