This dedicated environmental gas sensor report evaluates the performance of ten sensor technologies in detail - comparing their key characteristics and compatibility to five application areas. Key sensor technologies include metal oxide semiconductors, electrochemical sensors and infra-red sensors and optical particle counters, as well as photo-acoustic, printed and e-nose. These sensors have applications in growing markets for air quality monitoring for polluted cities to smart-offices. They play a key role in monitoring air quality as well as providing the necessary data for building automation services such as smart HVAC. This report includes over 30 company profiles from interviews with both major manufacturers and start-ups specializing in a range of different technologies. The report leverages IDTechEx's 15 years of experience in covering sensor technology, including interviews with major players, conference attendance, and bespoke projects and workshops on this topic.

 

IDTechEx 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 utilized 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 visualization, 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 commercialized 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 commercialized technology uses carbon nanotube inks printed on thin films. These advanced materials are a thousand times more sensitive than competitor technology. Optical particle counters are also shrinking, perhaps finally small enough to fit within wearables.

 

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.
