Scientists build sensor networks for your missing pens

CSIRO researchers have developed miniature sensors that track lab equipment, coffee mugs and staplers in the office.

Called Fleck Nano, the sensors build on CSIRO's existing Fleck technology that is being commercially produced for monitoring cows on farms.

Fleck sensors collect data like location and temperature. They form an ad-hoc mesh network, and communicate with static nodes and each other via radio waves.

CSIRO ICT Centre researcher Phil Valencia said they were similar to active RFID (radio frequency identification) tags, which also transmit signals autonomously.
