Grain of Sand Sky Spies

A new microchip roughly the size of a grain of sand that has the potential to glide across great distances is being touted as a breakthrough for aerial surveillance.

Key points: 

  • The devices are about the size of a grain of sand and can transmit wirelessly
  • Remote sensing technology was originally developed for warfare
  • The researchers hope the technology can be used to help monitor disease spread

Collaborating scientists from institutions including Northwestern University in the United States and Soongsil University in Korea have created what they believe are the world's smallest ever "human-made flying structures", which can be fitted with microchips and sensors and have the capacity to transmit data remotely.

The microchips can be dropped from the sky and potentially used to monitor environmental impacts and the spread of disease.The researchers, who published their findings today in the journal Nature. more
