Civil infrastructure is aging in many industrialized countries around the world. Autonomous monitoring of existing civil and industrial structures is of growing interest, as it has the potential to reduce cost for maintenance and repairs drastically, replace tedious, time-consuming and error-prone manual inspections, and allows to detect damage long before the human eye can. Especially in large structures, wireless sensor networks are preferable, as the deployment of cable-bound solutions is very costly. However, communicating with wireless sensors is challenging in many environments, as conventional communication techniques rely on electromagnetic waves, which cannot penetrate metal boundaries, e.g. if sensors are embedded within the structure. Furthermore, powering such devices with batteries requires regular battery replacements, which are costly when sensor nodes are in hard-to-reach places. Wireless power transfer is therefore an attractive solution to power sensor nodes in closed metal containers, such as pressure tanks or pipelines.
