“…Membrane displacement has been used at LAAS for pressure [4][5] temperature [6][7], stress [8][9] and radiation [10] transducers. For pressure transducer a high resistivity silicon membrane is fabricated above a planar half-wavelength resonator deposited inside a few microns depth glass cavity.…”

Passive wireless sensors with electromagnetic transduction are chipless wireless sensors that do not require electronic circuits or power. They are then good candidate for buried sensors or harsh environment applications. We validated at LAAS several transducers concepts with high sensitivity (pressure, stress, temperature, radiation) compatible with radar interrogation up to several ten of meters.

“…Such remote measurements require two main units: (1) the sensing unit, which is sensitive to any variation of the (physical or chemical) quantity of interest, and (2) the reader, which allows wireless interrogation of the sensing unit. Electromagnetic (EM) sensors operating in the microwave frequency range (see, e.g., [1][2][3]) are advantageously used here in the sensing unit while a Frequency-Modulated Continuous-Wave (FMCW) radar will serve in our future work as the reader (see, e.g., [4]). A reading range up to 58 meters of passive humidity EM sensors using such a radar was recently reported in [5].…”

A new microwave fully passive, chipless and packaged sensor for wireless pressure monitoring in harsh environments (such as, extreme temperature, radioactive and/or toxic environments) is proposed in this paper. The sensor consists of a planar microstrip resonator, which is electromagnetically coupled with a high resistivity and thin silicon membrane. Prototypes have been designed and fabricated using a photoresist intermediate layer for the silicon membrane bonding. The electromagnetic simulation of the system is also performed in order to predict the transducer performances. Measurement results using the packaged sensor are provided to experimentally validate the simulation results and the manufacturing process.

“…Wireless, chipless (without integrated circuit) and passive (battery-less) sensors could be a very convenient solution for the remote sensing of physical parameters in harsh environments. Applying the electromagnetic transduction principle many microwave and millimeter-wave sensors have been manufactured at LAAS-CNRS, such as pressure, temperature and strain sensors, as well as a radar-based solution for the wireless and long-range sensors interrogation (see, e.g., [1][2][3][4][5]). Very recently the authors have proposed a new concept of wireless, chipless and passive dosimeter which overcomes the limitations of state-of-the-art dosimeter [6][7].…”

Wireless hydrogen pressure dosimeter for nuclear high dose monitoring

et al. 2016

This communication reports the very first experimental results on an original wireless, chipless and passive (battery-less) sensor for monitoring high doses of nuclear radiation. The micro-sensor combines a miniature hydrogen pressure dosimeter with a passive microwave resonator. The pressure response is derived from S11-parameter measurement using vacuum and atmospheric pressure conditions. After e-beam irradiation (20kGy) the resonant frequency shift of the resonator ranges between 0.12%/kGy and 0.42%/kGy while the hydrogen pressure inside the cavity varies from 20mbar/kGy to 90mbar/kGy. No significant frequency shift is observed when using sensors during 6 months. These results demonstrate that a good hydrogen hermetic seal was fabricated during the manufacturing process of the constitutive micro-cavity.
