Flying Microchips The Size Of A Sand Grain Could Be Used For Population Surveillance

Posted by in categories: biotech/medical, computing

It’s neither a bird nor a plane, but a winged microchip as small as a grain of sand that can be carried by the wind as it monitors such things as pollution levels or the spread of airborne diseases.

Northwestern University says these are the world’s smallest human-made flying structures, and they could be used for monitoring the environment, population surveillance or disease tracking.
