North-Western University engineers have created an electronic microchip with the capability of flight.


  • About the size of a grain of sand, the new flying microchip (or “microflier”) does not have a motor or engine. Instead, it catches flight on the wind — much like a maple tree’s propeller seed — and spins like a helicopter through the air toward the ground.

  • A release by Northwestern University described these microflier as the “smallest-ever human-made flying structures”.
