Researchers use moths to airdrop sensors

Date: 12 October 2020 Tags: Miscellaneous
  • Researchers have developed a light-weight sensor system that can be carried by small insects like a moth to destinations that are dangerous or too small for humans to reach.
  • Once it reaches the destination, researchers can send a Bluetooth command to drop the sensor from its perch. The sensor is held on the insect using a magnetic pin surrounded by a thin coil of wire.
  • As soon as a researcher sends a wireless command to release the sensor, it creates a current through the coil that makes the magnetic pin to pop out the sensor.
  • The researchers believe that they can use this to create a network of sensors in a study area. This includes scattering sensors across a forest or farm to track them. They expect that this system can be deployed in different locations, including environmentally sensitive areas.
