There are lots of benefits to living in a big city, but cleaner air certainly isn’t one of them. Public transit and access to museums can’t wash away the stench of industry or the smog of urban traffic. If you want to take advantage of all a big city has to offer, you’re going to breath in some toxic fumes, that’s just the reality.
Or is it? Hand Tree is a concept currently working its way through the Electrolux Design Lab competition. It’s yet another example of wearable technology–a personal air purifier that’s worn around the wrist. Like its namesake, Hand Tree would inhale dirty air and exhale purified air. One may not make a huge difference, but millions all breathing in the same geographical area could make a serious difference to air quality.
Designed by Alexandr Kostin, the Hand Tree would be made from bioplastic and feature a carbon filter. With the onboard touchpad, someone wearing the high-tech bracelet could activate internal ionizers, which would suck in tobacco smoke, harmful gasses, chemical emissions, and even unpleasant odors. Once the air had passed through the filtration system, it would be re-emitted as fresh, clean oxygen.
A changing logo color on the touch pad would inform the wearer about the condition of the filter. A changing of the body lighting color would indicate the level of environmental pollution.
“Combining millions of personal air purifiers we can achieve the image of living in a forest. If every inhabitant in a big city would wear such a device, we would be all to breathe easily in a smoggy air,” writes Kostin.
