Inspired by nature, a team of engineers from Northwestern University developed the smallest-ever human-made flying winged microchip. It is about the size of a grain of sand.
By studying the aerodynamics of wind-dispersed seeds, such as the maple tree's propeller seed, the team came up with a design for the microchip that can behave with stability in its flight and ensure dispersal over a broad area for a long period.
There's no need for a motor or engine. This dispersed microflier could monitor air pollution, airborne disease, and environmental contamination.
Hopefully, there will be further developments in this research. Imagine the impact it can have in helping the health sector prevent the spread of disease.
