Flying Microchips The Size Of A Sand Grain Could Be Used For Population Surveillance

They optimized the aerodynamics of the microfliers so that "as these structures fall through the air, the interaction between the air and those wings cause a rotational motion that creates a very stable, slow, falling velocity," said John A.
