A Wireless Sensor Network dedicated to Structural Health Monitoring applications in harsh environments, which is the basis for the design of a communicating reinforced concrete, is presented. An autonomous wirelessly powered and battery-free LoRaWAN Sensing Node is highlighted here. The presented system measures temperature and humidity from its environment and transmits the recovered data to a Communicating Node, which interconnects the physical and digital worlds whilst simultaneously powering the Sensing Nodes via a far-field Wireless Power Transmission interface.
