A team of researchers and materials scientists from Northwestern University has developed microelectronic fliers that can collect environmental data. The size of the tiny fliers range from 40mm 9being the largest) to 0.4mm (being the smallest), and can collect various kinds of environmental data as they eventually fall to the ground.
So, as they can collect important environmental data by leveraging their unique properties and building materials, the scientists think that these should be perfect for environmental monitoring in the future. The team proposes that these electronic fliers can be dispersed in the air from an airplane or a drone and collect the data of an environment as they fall to the ground.
