Backscattering and Wireless Power Transfer in Battery-Free Sensors for Structural Health Monitoring of Reinforced Concrete Structures

Résumé

This paper presents an overview of the use of backscattering and Wireless Power Transfer in battery-free sensors for Non-Destructive Testing of reinforced concrete in order to ensure the Structural Health Monitoring of the structure of which it is the main material. A focus will be on a generic, battery-free Sensing Node. This last meets the Simultaneous Wireless Information and Power Transfer paradigm by being wirelessly powered and communicating wirelessly -simultaneously-thanks to electromagnetic waves. The security of wireless communications is also enhanced by backscattering and encrypting the power supply wave. This Sensing Node has been used in a Cyber-Physical System, and deployed and tested in a reinforced concrete beam with a power supply range of several metres and a wireless communication range -in Bluetooth Low Energy or LoRaWAN-of at least a few tens of metres.
