[2024] Self-power in-roller sensor systems for wind turbine generators

With the high-speed development of the Internet of Things (IoT), powering such a massive number of wireless IoT sensors with chemical batteries become more and more unpractical. To make the IoT sensors self-sustained, Piezoelectric Energy Harvesting (PEH) technology provides an excellent solution for powering the devices with a relatively long service time. By harvesting the ambient mechanical vibrations, PEH could generate a stable power source without wind or light.

Currently, the world's biggest bearing manufacturer, the SKF, collaborates with TU Delft to design a self-sustained smart IoT roller with PEH technology, which will be implanted in huge bearings, such as the bearing in the wind turbines. This thesis project will investigate the possibility of replacing the chemical battery with the Piezoelectric Energy Harvester in SKF’s smart IoT roller, called Sensor Roller.

The objective of this project includes the system design of the prototype energy harvester and power conditioning systems. If time allows, we'll do field tests at the SKF with the real bearings for wind turbine generators.
