Based on the electromagnetic transduction principle, a passive and wireless pressure sensor with a high sensitivity is designed. In the passive and wireless pressure sensor, the applied pressure generates a displacement of a thin membrane located above a planar millimeter-wave resonator. However, in previous works, the real membrane deflection has not been incorporated in the electromagnetic simulations and a uniform membrane deflection was assumed instead. In order to have a functional estimation of the real measurement unit, multiphysic simulations have to be performed with consideration of the electromagnetic and mechanical properties of the sensor. Therefore, this paper presents a progressive approach to derive an accurate functional approximation of the sensor under the real working condition and to take into account the real deflection of the membrane when applying a pressure.

“…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 batteries. Recently the first sensor based on the electromagnetic (EM) transduction principle has been reported [1]- [3]. The operating mode of such sensor is the following: an applied pressure force generates a displacement of a thin membrane located above a planar millimeterwave resonator.…”

“…Such displacement causes the modification of the electromagnetic field distribution around the resonator and a shift in resonant frequency occurs. Pressure cell prototypes with 50µm high resistivity silicon membrane were fabricated and a sensitivity of 370MHz/bar has been measured [3]. In [4]- [5] the interrogation of such passive sensors by a frequency-modulated signal for the remote measurement of pressure is proposed but no experimental proof of concept has been reported.…”

“…The LAAS-CNRS has proposed the first pressure sensor based on the EM Transduction principle [1] (see also, [2,3] for more details dealing with the simulation, the fabrication and the measurement of such passive EM transduction based Pressure sensor) and its wireless interrogation by RADAR signal for the remote measurement of the pressure [4]. The Electromagnetic transduction terminology was given to this kind of sensing transducer because it's based on the following physical phenomenon: The sensor device is composed of a high resistivity silicon membrane which undergoes a deflection when applying a pressure.…”

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 microsensors 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 reported and brings an original solution for the passive EM transduction based Micro-sensor identification problem. Index Terms -Reconfigurable Multi-band Scatterers, multiband scatterers RCS, EM Transduction based Wireless Sensor network, FMCW Radar.
