Market research organisation IDTechEx has recently released its report “Gas Sensors 2022-2032: Technology, Opportunities, Players and Forecasts”, evaluating the technological and application trends within the gas sensor industry. Tess Skyrme, IDTechEx Technology Analyst, outlines the key points

as sensors represent both, an established as well as an emerging industry, creating a complex web of technologies
and applications. Detection methods span a diverse technology landscape, ranging from semiconductor and optical to acoustic and photo-ionisation. Determining which technologies are best suited to the broad application space, including rapidly-growing IoT markets, requires understanding of sensor attributes such as sensitivity, selectivity, cost and size.
First in air-quality monitoring Gas sensing will be required by many sectors, including the factory, home and city of the future. Vast sensor networks will span across cities and be integrated into homes to enable greater automation and predictive maintenance through continuous monitoring of parameters, such as air quality, air-borne viruses and even climate change. To achieve some of these requirements,
there are new sensor technologies emerging, to act as a digital replacement for the nose and brain, capable of objectively quantifying smells. Moreover, the size and

power of these so-called ‘e-noses’ are small enough to allow them to be integrated into everything from cars and fridges to smart- home products and even phones. Sensors small enough to fi t inside a smartphone sell in high volumes already, and now we are beginning to see micron- scale gas sensors emerging from the lab. Demand from the public for air-quality sensors spiked during the pandemic, a trend set to continue into the future. Newly-commercialised technology uses carbon nanotube inks printed on thin fi lms – advanced materials that are a thousand times more sensitive than competing technologies.
The global market for gas sensors is
forecast to reach $8.4bn by 2032, mostly driven by the mass digitisation of air quality.
Forecasts IDTechEx forecasts a growing market for environmental applications worldwide, with an increasing proportion of revenue generated from infra-red sensors and optical particle counters. It is anticipated that a consumer market for digital smell will become more established, with existing technology combined with AI utilised in white goods and quality control. The most disruptive technologies are
predicted to be printed acoustic gas sensors, which hold the most promise for ultra-low form-factor applications such as smart packaging and wearables.
