Description: Future Challenges & Roadmap: Driven by new, large-volume applications such as wearables, the so far established gas sensing technologies undergo new technical challenges such as size/cost reduction, low power, increased selectivity, multi gasses detection and wireless communication. The trend is also to have multiple sensors (“environmental combos”) in a single package for cost/size issues. The goal is to have an “environment-sensitive sensor module” with different sensors: 3 to 4 different gas sensors, pressure sensor, microphone, humidity, and temperature.

This will be an “open” combo (at the opposite of inertial combos that require vacuum packaging for example).

CONCLUSIONS & OUTLOOK
The gas sensors market is still a fragmented business with many players—TOP 3 “only”
accounts for 24% of total market in 2014.
It attracts many new entrants, coming in a fabless/fablight model
These new entrants announced ramp-up in volume very soon (AlphaSzenszor, KWJ, AMS …)

Gas sensors cost & miniaturization is a driving force for consumer and industrial
applications (portability).
It opens the way to new approaches: MEMS, optical integration, new approaches based on CNT.
Arrays of 3–4 sensors are an interesting option to detect many gases to compete with too complex e-noses

Trend is also to have multiple sensors (“environmental combos”) in a single package for
cost/size issues.
The goal is to have an “environment-sensitive sensor module” with different sensors: 3 to 4 different gas
sensors, pressure sensor, microphone, humidity and temperature.
This will be an “open” combo (at the opposite of inertial combos that require vacuum packaging for example).
