A novel design of a highly sensitive wireless passive radio frequency strain transducer is presented based on a patch antenna loaded with an open loop that is capable of sensing strain remotely. The new idea of utilizing a cantilever at the gap of the open loop significantly improves the sensitivity of resonant frequency shifts. In measurements, the(More)

A wireless passive ultrasensitive temperature transducer is presented in this paper. T he transducer consists of micro bimorph cantilevers (Aluminum-Silicon) and split ring resonators, operating at millimeter wave frequencies around 30 GHz. As the temperature changes, the bilayer cantilevers deflect and thus alter the resonant frequencies of the resonators.(More)
The LCPR or Rotated Connective Flap is a simple mucogingival surgery technique that permits the to recreate, of an interdental papilla by the contribution of the vascularized connective pedicle. Keeping a good vascularization of the flap by its pedicle and its good recovering by some superficial flaps, seems to insure a long dated stability of the(More)
A highly sensitive wireless passive radio frequency strain transducer is designed and developed based on a patch antenna loaded with an open loop. A novel idea of utilizing a cantilever at the gap of the open loop significantly improves the sensitivity of resonant frequency shifts. The ground plane allows the sensitivity of the sensor to be independent from(More)
A scale changing approach is proposed for the electromagnetic modeling of phase-shifter elements used in reconfigurable microelectromechanical system (MEMS)-controlled reflectarrays. Based on the partition of the discontinuity plane in planar sub-domains with various scale levels, this technique allows the computation of the phase shift from the simple(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)
In this paper, we propose the first dual-band retrodirective reflector array using Substrate Integrated Waveguide (SIW) and inkjet-printed technologies on flexible low-cost substrates, such as paper, for operability around 3.6GHz and 5.8GHz. In addition, it offers the versatility of multiband retro-directive designs potentially covering numerous RFID(More)
Radio frequency identification (RFID) technology has enabled a new class of low cost, wireless zero-power sensors, which open up applications in highly pervasive and distributed RFID-enabled sensing, which were previously not feasible with wired or battery powered wireless sensor nodes. This paper provides a review of RFID sensing techniques utilizing(More)
The concept of Scale-Changing Network is reported for the electromagnetic modeling of complex planar structures composed of a collection of metallic patterns printed on a dielectric surface and whose size covers a large range of scale. Examples of such multi-scale structures are provided by multi-band frequency-selective surfaces, finite-size arrays of(More)
This paper presents the design and experimental validation of an original single layer planar wideband microstrip antenna for C-band airborne applications. This antenna printed on a 787μm-thick substrate exhibits wideband performance and inclined radiation patterns. The measured results are in good agreement with the simulated ones in terms of bandwidth(More)
