This paper presents a proof of concept of an original identification technique of passive EM sensor cells. Previous works published by the authors have shown the feasibility of high sensitivity passive sensor Microsystems based on the electromagnetic transduction principle [1]. More, other works, published by the same authors, have demonstrated the(More)
In this paper a new type of low cost, smart and high sensitivity pressure micro-sensor is designed based on electromagnetic transduction principle, which can be used for long distance covering measurement. As it will be shown in this paper, the resulting pressure cell presents a high sensitivity to the applied pressure, is compatible with fully passive(More)
The wireless measurement of various physical quantities from the analysis of the RADAR Cross Sections variability of passive electromagnetic sensors is presented. A millimetre-wave Frequency-Modulated Continuous-Wave RADAR is used for both remote sensing and wireless identification of sensors. Long reading ranges (up to some decameters) may be reached at(More)
A wireless, passive, and ultrasensitive temperature transducer is presented in this paper. The transducer consists of split ring resonators loaded with micro-bimorph cantilevers, which can potentially operate up to millimeter-wave frequencies (above 30 GHz). As the temperature changes, the bimorph cantilevers deflect and result in a shift of the resonant(More)
More and more growing demand of the industry for implementation of completely passive sensor system is observed. In many rising applications a wired connection between the sensor and the data processing system cannot be installed and a need increases for wireless sensors that require no active elements such as power supplies, signal processing circuits or(More)
In this communication, the new and latest results relative to an original passive electromagnetic micro-sensor for wireless pressure monitoring application are presented. This micro-sensor uses the electromagnetic transduction principle. The sensing element is a flexible high resistivity silicon membrane located above a coplanar quarter-wavelength resonator(More)
In this communication we present a new and different approach based on electromagnetic transduction principle, which can be used for long distance covering pressure measurement. Previous work reported by the authors has validated the principle of the electromagnetic transduction for 400µm silicon membrane thickness and with the hypothesis of uniform(More)
In this paper and for the first time, the use of multi-band scatterers RCS is proposed for the remote identification of Electromagnetic Transduction based micro-sensors in a wireless sensor network. The potentialities of such technique are described and original multi-band scatterers shapes and configurations are investigated. This work is the first to be(More)
In this paper, we present the wirelessmeasurement of various physical quantities from the analysis of the radar cross section variability of passive electromagnetic sensors.

Temperature sensing is critical in many automotive, medical, and industrial systems for applications such as engine operations, space shuttle and aircraft in-flight conditions, and road and bridge health. A passive wireless temperature sensor would enable remote sensing and long term monitoring for those applications. Most existing temperature sensors(More)
