Airdropping sensors from drones and insects
Researchers at the University of Washington say they have created a wireless sensor system that can ride on the back of a moth.
it begins rotating around the corner with the battery, generating additional drag force and slowing its descent. That, combined with the sensor’s low weight, keeps its maximum fall speed at around 11 miles per hour, allowing the sensor to hit the ground safely.

The researchers envision using this system to create a sensor network within a study area, for example, using drones or insects to scatter sensors across a forest or farm that they want to monitor. Once a mechanism is developed to recover sensors after their batteries have died, say the researchers, they expect their system could be used in a wide variety of locations, including environmentally sensitive areas.

Looking ahead, the researchers plan to replace the battery with a solar cell and automate sensor deployment in industrial settings. For more, see " Airdropping sensor networks from drones and insects ."
