Energy-independent, extremely efficient sensor nodes are one of the key technologies for the “Green Internet of Things” and “Smart Objects”.

Pursuing a high-performance logistics solution, this project involves the implementation of an asset tracking system, including the development of the electronics for the gateways and location beacons, as well as a miniaturized wireless tag integrated into the tracked asset. An energy-saving wireless solution is especially important for this application. The tag electronics consist of a tri-band wake-up receiver with a current consumption below 10 µA, plus an efficient two-band transmitter. The tag will be completely powered with energy harvesting technology for permanent autonomous operation.

The energy-saving electronics solutions developed in this project will eventually be suitable for a wide range of applications such as logistics, building automation, intelligent lighting, electronic labels, remote maintenance and control and wireless sensor networks.
