—Wireless sensors market is growing very fast these last years tanks to the availability of cheap, small and efficient micro-sensors, batteries, analog and RF circuits, and to the presence of standardized communication protocols. Even if these active sensors are very attractive for a lot of applications, they suffer from weak energy autonomy and they are(More)
—The effects of bias current in the sensing layer of resistive Metal-Oxide (MOX) sensors toward gases have been investigated. The behavior of a WO 3 thin film deposited by sputtering has been studied. In a first time, while the working temperature is kept constant, it has been found that tuning the polarization of the MOX layer induces changes on its(More)
In this paper, we present the wireless measurement of various physical quantities from the analysis of the radar cross section variability of passive electromagnetic sensors. The technique uses a millimeter frequency-modulated continuous-wave radar for both remote sensing and wireless identification of sensors. Long reading ranges (up to some decameters)(More)
A general bottom-up modeling strategy for gas sensor response to CO, O(2), H(2)O, and related mixtures exposure is demonstrated. In a first stage, we present first principles calculations that aimed at giving an unprecedented review of basic chemical mechanisms taking place at the sensor surface. Then, simulations of an operating gas sensor are performed(More)
—A pressure sensor demonstrator has been designed and mounted using a simple analog-digital BiCMOS converter and a capacitive Silicon–Pyrex sensing cell. The measurements as a function of pressure and temperature have enabled to evaluate the efficiency of a ratiometric scheme to self-compensate thermal drifts and nonlinearities. The best demonstrator is(More)
