Industrial designer Kevin Chiam has created a 3D-printed wearable air purifier that is deigned to remove air pollution from around the user using a water vapour.
Airtomo is a small clip-on device that can be attached to a bag, pocket or shoe, and comes in a series of bold colours.
Chiam has created a working prototype for Airtomo and is developing concepts for purifiers in ankle and neckband form.
Airtomo works by releasing atomised water vapour into the air. This ultra-fine mist of water droplets binds to particulate matter in the air, forming a heavy aggregate that drops to the ground.
The water vapour is fine enough that it doesn't get the user's clothes damp, explained Chiam, and the pollution particles on the floor can then be swept away.
Designed to be used on the go, Airtomo is charged with a micro-USB cable and can be replenished with water wherever necessary.
Airtomo is made from a combination of 3D-printed parts along with a bespoke circuit boCard, a battery and an ultrasonic transducer disc that atomises the water into fine droplets.
Chiam also plans to make Airtomo modules that can be placed on the walls to improve the air quality.
A small scout module would detect movement from passing commuters using a passive infrared sensor. After receiving this information via WiFi, the main module would release water vapour into the air.
