Garbage cans that use a built-in level sensor to notice when they need to be emptied – and report this to the garbage disposal? These are just two striking examples of the Internet of Things, or IoT for short: objects that connect to the Internet and exchange data with each other. Both in the private and in the industrial sector, the number of such wirelessly networked devices is increasing rapidly. But in order to be reachable at all times, the radio receiver of the devices must be switched on permanently – which limits the battery life of small, battery-operated IoT nodes to a few weeks.Hundred-fold battery life, prompt reactionThe RFicient® chip from the Fraunhofer Institute allows an enormous leap forward for Integrated Circuits IIS. “With our chip, we can save 99 percent of the electricity – a battery that lasts a good month with conventional technology then lasts ten years,” enthuses Dr. Frank Oehler. Nevertheless, and this is what makes the development so appealing, the sensor node is always ready to receive: it needs just 30 milliseconds to react to a signal with an action. While other wake-up receivers are often switched off for minutes and sometimes only react when it’s too late, the RFicient® chip guarantees an immediate reaction. This is not only important for time-critical applications, but also where many services are running simultaneously or many individual nodes are queried – for example in the airport, in the train station, in the football stadium entire team, dr. Frank Oehler, Dr. Heinrich Milosiu and Dr. Markus Eppel was awarded the Joseph von Fraunhofer Prize. In addition to the complete process chain from the idea to implementation, it was above all the special social relevance that convinced the jury: After all, the number of wirelessly networked devices is skyrocketing, along with the associated consumption of energy and resources. Technology has already been developed from the first idea to a commercially available standard chip.
