    • Abstract:
      International audience ; This communication reports the design of a packaged passive microwave sensor for measuring applied pressures up to 3bars in highly reflective (metallic) environments. The technological fabrication process is detailed as well as the packaging of the device, which shows an outstanding 440MHz/bar sensitivity between 0.75 and 2.8bars. A microwave Frequency Modulated Continuous Wave (FM-CW) radar is then used for remotely reading the applied pressures. A large full-scale range of 12dB is obtained with a sensitivity of 5.7dB/bar and an estimated precision of ±10mbars between 0.5 and 2bars.
