Scientists Have Made A Flying Microchip The Size Of A Grain Of Sand

Engineers at Northwestern University have unveiled their latest invention - a flying microchip the size of a grain of sand.

Called the 'microflier', it's the smallest flying structure ever made by man.  

The microflier takes flight by catching the wind. Researchers got the idea from aerodynamic seeds - like the 'propellor seeds' that come from maple trees, or star-shaped Tristellateia seeds.

Microfliers could potentially be used for wireless communication, or to track things like air pollution or even airborne viruses.

How do you feel about tiny grain-of-sand-sized microchips floating in the air? What would you use the technology for?
