IDTechEx has been covering the broad topic of sensor technology since 2008. We have interviewed a wide range of the major players over the years, attended multiple conferences and delivered both consulting projects and workshops on this topic. This dedicated gas sensor report evaluates the performance of ten technologies in detail - comparing their key characteristics and compatibility to five application areas. It includes 20 company profiles from interviews with both major manufacturers and start-ups specialising in a range of different technologies.

 

We have developed 10-year market forecasts for each technology and application sector, presented by both revenue and volume. We forecast 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 and acoustic gas sensors, which hold the most promise for ultra-low form factor applications such as smart packaging and wearables.

 

Gas detection methods span a diverse technology landscape, ranging from established approaches such as metal oxide detectors to innovative emerging approaches such as acoustic gas sensing. Determining which technologies are best suited to the broad application space, including the rapidly growing market for IoT applications, requires analysis of attributes such as sensitivity, selectivity, cost, and compactness. This report comprehensively explores the technology-market fit for each technology and application, providing insight into the gas sensing requirements for the home, factory, and city of the future.

 

 

 

 

 

 

Vast sensor networks spanning our cities and integrated into our homes will offer greater automation and predictive maintenance, through continuous monitoring of parameters including air quality. Once a concern reserved for industrial facility managers, sophisticated air quality monitoring with gas sensors will both inform policy and enable consumers to make more informed choices regarding issues such as pollution, air-born pandemics and even climate change.

 

Widely distributed gas sensor networks will enable automated ventilation of schools, homes, monitor urban air quality, change government policies, control traffic, and more. The era of gas sensor data as technical information only accessible to scientists is ending, being overtaken by sensors which are easy to use, low power and affordable.

 

Mass-digitization of gas measurements will rely on software which goes beyond visualisation, adding value through improved sensitivity, companion apps and closed loop control. We assess the hardware and business models enabling continuous measurement and identify commercial opportunities within environmental monitoring and air quality.

 

 

There is no denying that aroma is important to us. The quality of food and drink is often first assessed just after we smell it. This ranges from whether we think yesterday's milk is safe, to expert opinions on the merits of a wine vintage. Historically the human nose has been our only means of identifying aromas - until now.

 

New sensor technology claims to act as a digital replacement to the nose and brain, capable of objectively quantifying smells. Moreover, the size and power of these so called 'e-noses' is small enough to allow them to be integrated into everything from cars and fridges to smart home products and phones. But how does digital smell work, and does the technology readiness level match the hype?

 

We not only explain the principle of 'e-nose' technology but compare the performance of newly commercialised devices - extracting realistic opportunities from marketing hype.

 

 

 

Sensors small enough to fit inside a smart phone sell in high volumes, and micron scale gas sensor technology is emerging from the lab. Demand from the public for air quality sensors spiked during the pandemic, a trend set to continue beyond 2022.

 

Newly commercialised technology uses carbon nanotube inks printed on thin films. These advanced materials are a thousand times more sensitive than competitor technology.

 

We benchmark the performance and application of this and other early-stage technology against established techniques. Alongside an in-depth review of printed sensors, we provide a roadmap towards ultra-miniaturized gas sensors.
