Built into the smallest flying object, it is a VIDEO – News microchip

by drbyos

A microchip with wings is the smallest flying structure built by man: inspired by the seeds of plants dispersed by the wind, it could open up to a new generation of sensors for the environment and biomedicine, without batteries and wireless. This was done by researchers from Northwestern University in Evanston, whose study is published in the journal Nature.

Taking inspiration from wind-dispersed seeds, researchers led by John Rogers designed flying structures ranging from microscale (less than 1 millimeter) to macroscale (greater than 1 millimeter). Using simulations and using the wind tunnel, the researchers studied how the aerodynamics of these flying objects are changed as the diameter, structure and type of wings change.

For the most part, microchips with wings are the size of a grain of sand and have no motor, but they fly on the wind like gliders and spin like helicopters. The aerodynamics of these structures have been designed to ensure that they descend in a controlled manner even from high heights. This also stabilizes the flight, ensuring dispersion in a wide area and increasing the interaction time with the air, making it ideal for monitoring air pollution.

Flying microchips are composed of two parts: the wings and the functional electronic components. In the finota wave experiments, researchers have corrected sensor microchips to monitor the acidity of the air or exposure to the sun at different wavelengths. The next goal is to make sure that these tiny machines can gradually dissolve in water over time, once they are no longer needed.
