Winged Microchip-Smallest Human made flying structure
- Northwestern 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.
- The research has been published in Nature and is featured on the cover of the journal.
