Sens4Bee – Monitoring colony health with RFID sensors capturing data in beehives and on individual bees

Silicon technology is used to develop an extremely miniature lithium battery and solar power module. Micro-Sensys GmbH is working to integrate these with tiny sensor transponders and data loggers with RFID interfaces into a module that is lightweight and small enough to be carried by individual worker bees.

On the trail of bee mortality with energy-autonomous sensors

Bees not only provide us humans with honey, but thanks to the pollination of herbs, shrubs and trees, they are significantly responsible for the preservation of species. As a result, they generate around 1.6 billion euros for agriculture and food production in Germany.
