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

Year: 2025

Type: conference-paper

Abstract: 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.
