Abstract(s) :
(Anglais) Nuclear environments are hazardous and possibly life-threatened, which means that they must be monitored. However, the risk for human beings and nature implies that most of individuals are not ready to perform the monitoring by them-selves. A solution to overcome this situation consists in using Wireless Sensor Networks (WSNs), which are groups of autonomous sensors wireless connected together that allow to perform long-distance monitoring. Still, a remaining issue is the battery replacement, which requires human intervention. Fortunately, it can be avoided thanks to energy harvesting. The aim of this work is to present an overview of energy harvesting methods for powering WSNs and their applicability to nuclear environments monitoring.
