  • In Japan, Men's 4x100m relay athlete Shingo Suetsugu wore Dyson’s prototype air quality backpack and travelled around Tokyo and Kanagawa, to investigate the air conditions in his daily life.

     

    He is part of a group of five other athletes who were training towards the world’s largest sporting event this July – Annette Edmondson (Australia), Thomas Röhler (Germany), Dafne Schippers (Netherlands), Anastasia Pavlyuchenkova (Russia), and Mujinga Kambundji (Switzerland) – who participated in Dyson’s wearable air monitoring technology project. They used Dyson’s prototype air quality backpack for a period of three days, using it all day long while completing different activities, to collect data to track their personal exposure to air pollution.

  • Shingo visited his usual practice base, areas near his home, as well as sightseeing spots in Tokyo, running courses, and places to visit when playing sports.

     

    Dyson scientists initiated the project to explore how exposure could affect wellbeing. Re-working existing technology used in Dyson purifiers, the Dyson air quality backpack is a portable air-sensing device. Armed with on-board sensors, a battery pack and GPS, it is able to measure pollution data on the move.

  • Data findings

    Dyson engineers analysed the findings by pairing the air sensor and GPS data from the backpack with the athletes’ diary entries, where they documented their activities and observations in the period wearing the air quality backpack.

     

    On Shingo’s route, the air quality was clean at a stadium and along the beach but spiked when he was near busy roads, an indication that the backpack may have picked up the Nitrogen Dioxide (NO2) emitted from vehicles.

     

    Exhaust gases from cars is one of the sources of NO2, which can increase pollution levels when along congested roads. It can also be detected at traffic lights and pedestrian crossings where many vehicles are stationary.
