Objective Only partial validations have been made. The system operates correctly in free air and uses commercially available components. An original system, energetically efficient, has been designed to solve the problem of the wireless data return. The experiments with the sensor embedded in concrete have shown that the actual version is too sensitive to the presence of metallic wires. A new version is now being developed that will first increase the energy transfer, and above all, the voltage outgoing the sensor antennas, and secondly increase the sensitivity to strains in the three orthonormal directions by at least two orders of magnitude. The main advantages of this system are the ease of installation, the survivability of the network to major cracks, the reliability, stability, and lifetime associated with the design and the operational mode, and, if a silicon ASIC is developed, the low cost/unit.
