Engineers at Northwestern University in Evanston, Illinois, US, have designed electronic microchips that can fly. These flying microchips, or microfliers, are the size of a sand grain and can fly without any motor or engine, much like a maple leaf or air-borne seeds of plants. These are the smallest-ever human-made flying structures. The microflier's aerodynamics is designed so that it falls in a stabilised way at a slow velocity. This ensures that it stays airborne for a longer time and disperses over a broad area. These features make it ideal for monitoring air pollution and airborne diseases. The research was published in the Nature journal.

Northwestern University's John A. Rogers, who led the device's development, said in a press release, "Our goal was to add winged flight to…
