2018 Edition. In Device Technology of the Year

Through a partnership with precision MEMS foundry Rogue Valley Microdevices, AerNos offers an ultra-miniaturized, affordable gas sensor technology that can monitor air quality on an individual level.

What’s was the challenge?
Monitoring the air we breathe is an enormous challenge because air quality varies dramatically, depending on location. That is why having the ability to measure air quality on an individual basis is so important. Armed with information on airborne toxins in our surroundings, we can act to reduce exposure by changing our location. We can also employ automated air purification systems, automated ventilation systems, and connected IoT devices that reduce emissions when air quality is poor.

What do they offer?
AerNos’s MEMS-based 3 mm x 3 mm sensor chip uses hybrid nanostructures to simultaneously detect specific gases in indoor and outdoor environments. In addition to their small size, low power and affordability, AerNos gas sensors can detect multiple gases simultaneously -- a major improvement over competitors that can detect just one-two gases.

How did they do it?
Rogue Valley Microdevices fulfilled AerNos’ requirements: selectivity, sensitivity, low power consumption, and stability of its technology, all while using nanomaterials, including carbon nanotubes — which are highly sensitive to the environment. Rogue Valley Microdevices used nanomaterial doping processes to create nanostructures where shape, size, density and location of nanomaterials are fabricated with precision. The AerNos gas sensor is the result of this manufacturing partnership.
