Measuring and monitoring the state of infrastructure built with concrete, such as buildings or bridges, is important to prevent damages or other serious issues. Some requirements for monitoring devices are long operation lifetime, robustness against

The reduction of energy consumption is an important requirement in low-power nodes such as those used in LPWAN or WPAN. This is even more important when dealing with nodes powered by harvested energy. It is therefore important to investigate how ener

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 temp

Information collected by sensors can be sent to servers using LPWAN nodes. In many cases, energy autonomy is desired for such nodes, in order to avoid the costs of maintenance. This is not always easy to achieve. We will discuss the energy requiremen

We have been working on methods to provide enough energy for the monitoring of civil infrastructure such as walls or bridges. In this presentation we will discuss the status of that work. More specifically, we will show and discuss measurements resul

Sigfox is one of the popular LPWAN technologies used in the Internet of Things. As in the case of many other wireless protocols, Sigfox nodes are mainly powered with batteries, which leads to important maintenance costs and slows down its acceptance.
