Energy harvesting Technologies for IIoT Applications in Electricity Grid Management — •Joana R. C. Faria and Francisco J. A. Cardoso — LIBPhys - University of Coimbra, Portugal

Being based on the significant advances in different technological areas - sensors, Microsystems, wireless networks, and web service programming -, the Internet of Things (IoT) represents a concept that enables data produced at a number of different locations to be aggregated in a central database. A single IoT device can be useful on its own, but it is the combination of information from numerous devices that tends to increase their intrinsic value, thus underlying the concepts of smart buildings, factories and cities.

The Industrial Internet of Things (IIoT), which is a major tool for the upcoming Industry 4.0, has grown at a faster pace because it can help businesses operate more efficiently, make better informed decisions and unlock new revenue sources. Numerous connected devices demand innovative ways to supply their power demands in a permanent and sustainable way. Energy harvesting technologies reuse ambient energy which is otherwise wasted, creating a practical and self-sufficient solution for IoT power supply.

Here, it is shown that opportunities for energy harvesting technologies exist even in electricity grids. Energy harvesting from two energy sources in the surrounding environment (solar and thermoelectric) are presented in different application contexts of electricity grid management, including the respective experimental results.
