Even for tiny wireless sensors it is important to find sustainable and efficient solutions to generate energy. This is where Energy Harvesting comes in. 💪

By integrating energy harvesting technologies, our wireless sensors can harvest energy from their immediate environment to recharge their batteries or even operate independently of batteries. This can extend the life of the sensors, lower maintenance costs, and reduce environmental impact.

As the second of three final theses on energy harvesting at i4M technologies GmbH, Florence Kiehl analyzed two prototypes for electromagnetic energy harvesting in her master’s thesis. These systems supply a sensor on a rotating shaft with energy. The goal is to ensure enough energy to operate our wireless measurement technology even at low rotational speeds. Their approach is much simpler and more robust than the inductive couplings commonly used in telemetry. The different parameters of an electromagnetic system were determined and their influence on the power output was evaluated. The results of this master’s thesis provide us with a very good basis for the development of further electromagnetic power generation systems, some of which are already being incorporated into ongoing developments.

Florence, congratulations on successfully passing your master’s exam! 👏 We thank you for the great work and wish you all the best for your future. 🎉
