Abstract

The energy autonomy of wireless sensors is crucial especially for buried or inaccessible sensors that are often the case in SHM applications. This problem can be overcome by using classical passive sensors (RFID or SAW sensors) but they suffer from a problem of low reading distances (<10m). For few years emerged a new kind of passive sensors using electromagnetic transducers, combining very high autonomy, high resistance to harsh environment, potential interrogation distance higher than SAW sensors and wide variety of sensing principles. We started to work in this new research field in 2005 and several sensor principles have been validated in our lab (pressure, temperature, stress) with FMCW (Frequency Modulated Continuous Wave) Radar interrogation.
