|Title:||Battery-free LPWAN nodes for bridges and walls|
|Conference details:||Embedded World Conference 2021, online, 1.-5. März 2021|
|Subjects:||Energy harvesting; Energy autonomous; TEG; Low power; Booster; Power management|
|Subject (DDC):||621.04: Energy engineering|
|Abstract:||This presentation builds on an early work where we evaluated the potential of harvesting energy from concrete walls using temperature differences. We have now built and installed several LPWAN nodes that are powered solely from TEGs, using small temperature differences. With efficient harvesting, those nodes can scavenge sufficient energy to sense parameters in the civil infrastructure environment and communicate with gateways that are several kilometres away. This brings battery-free monitoring of walls and bridges one step closer to reality. After giving an overview of the technologies involved and discussing the basis of TEG harvesting, we will present first results and early conclusions of several weeks of measurement activity.|
