green bangle by andrew wee from philippines

We cannot see the harmful microscopic particles floating in the air we breathe. People may be complacent because they don’t see the threat. Thus, it is imperative to provide a visual warning, which the green bangle provides.

It measures the level of air pollution with sensors or receives signals from air-pollution measurement systems and translates them by glowing into the corresponding color code.

Thus, it warns not only its wearer (especially those with respiratory problems) but others as well. A few people wearing it can highlight an area’s air quality and have a galvanizing effect on the community, which leads to more concrete actions. A red zone will sense more urgency to clean up; a green zone becomes a highly desirable place to live in.
