Wireless Sensing of Concrete Setting Process

An RFID-based wireless system to measure the evolution of the setting process of cement-based materials is presented in this paper. The system consists of a wireless RFID temperature sensor that works embedded in concrete, and an external RFID reader that communicates...

Variable Capacitive Antenna Loading for Embedded RFID Sensors

Authors: Giselle González, Lluís Jofre, Jordi Romeu, Ignasi Cairó In this paper, a self-adaptive folded dipole antenna to work embedded in media with changing physical and chemical properties for RFID applications is proposed. Self-adaptability is provided by taking...
