Could Tiny Flying Computer Chips Monitor the World? They’re here!

A team at Northwestern University has developed a model based on the design of seed dispersal in nature

A Northwestern University team is developing electronic chips as small as a grain of sand, equipped with wings like those of wind-dispersed seeds. The hope is that these microfliers will monitor pollution and contamination — and surveil crowds via ultra-miniaturized equipment: 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. By studying maple trees and other types of wind-dispersed seeds, the engineers optimized the microflier’s aerodynamics to ensure that it — when dropped at a high elevation — falls at a…
