摘要
A wireless sensor for detection or measurement of at least one specific component present in a gaseous or liquid mixture, the gas sensor including at least one sensor cell, having a high-electron-mobility transistor having a source and a drain with a gate intercalated between source and drain. The at least one sensor cell having a high-electron-mobility transistor is associated with at least one split-ring resonator with at least one respective slit and connected between, on the one hand, the drain and on the other hand, the gate or the source of the at least one sensor cell, the sensor detecting a change in the intensity or the frequency of resonance as a function of the presence and/or of the concentration of the at least one specific component in the gaseous or liquid mixture.
