Vehicle Emissions: New sensor technology to improve air quality in cities

13.08.2019

Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.

Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission Sensing), an international research consortium is working on new contactless exhaust measurement methods that will enable municipalities to take emission-reducing measures.

In concrete terms, the researchers want to develop new sensors that can be attached to roadsides, crash barriers or traffic signs which detect the exhaust emission of passing vehicles in a matter of seconds.

"We want to monitor vehicle emissions in cities and environmental zones under real conditions, without having to interfere with free-flowing traffic," explains Alexander Bergmann, head of the Institute of Electronic Sensor Systems at Graz University of Technology. He and his team are primarily responsible in the project for all aspects of particle measurement – a field in which the Institute is one of the world’s leading institutions.

Manifold possibilities of traffic regulation

“The aim is to detect the exhaust class of each individual vehicle using these measurements,” explains Bergmann. For example, cities could introduce an emissions-based city toll: the higher the emissions of the car, the higher the charge would be. Entry permits into environmental zones could also be monitored automatically, in which automatic barriers only open if the pollutant emissions of the approaching car are within the standard range.

Finally, sensor technology could be used to identify and pull out of traffic those vehicles in which engine performance and thus pollutant emissions have been increased with manipulated particle filters or chip tuning.
Tuning forks as particle measurers

Bergmann expects low-cost remote sensors for emission measurement to be ready for series production by the end of the 2022 project at the latest. However, he already refers to the first promising tests at the institute in which conventional tuning forks are used.

The particles between the fork are excited through laser pulses, which in turn produce an acoustic signal and begin to "sing" in the truest sense of the word. Each individual particle emits acoustic signals which are recorded and played back by the tuning fork. The more particles there are, the louder the sound becomes. The volume can then be used to determine how many particles are in the environment.

The technology is already being used successfully for gas measurements. "Our institute was now able to show for the first time that this also works with particles and could be a possibility for a low-cost sensor," said Bergmann. The researchers at TU Graz hope that the measuring method will also prove its worth in the metropolises of Milan, Prague and Krakow, where the investigations will be carried out in live operation as part of the CARES project.

The research project CARES is funded within the Horizon 2020 Research and Innovation Programme of the European Union with EUR 3,326,735.50 and is anchored in the Field of Expertise "Information, Communication & Computing", one of five strategic focal areas of Graz University of Technology.

Im Focus: Images from NJIT's big bear solar observatory peel away layers of a stellar mystery

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
