The 'Microflier' is about the size of a grain of sand.
Researchers at northwestern university have developed a winged microchip which is the smallest-ever human-made flying structure. Comparable in size to a grain of sand, the new flying microchip or microflier doesn’t use a motor or engine to fly, instead it references a maple tree’s propeller seed and catches flight on the wind by spinning like a helicopter.
The microflier’s aerodynamics ensure that once the chip has been dropped at a high elevation, it will fall at a slow velocity in a controlled manner. The behavior stabilizes its flight, ensures dispersal over a broad area and increases the amount of time it interacts with the air, making it ideal for monitoring air pollution and airborne disease.
