Testing the sensor's performance in ultrahigh vacuum and at room temperature across a broad pressure spectrum.

Main Results:

The sensor achieved ultrahigh sensitivity, detecting pressure differences as small as 1 × 10^-7 mbar in the ultrahigh-vacuum region.

Both fundamental and higher-order resonant frequencies were effective, with higher-order frequencies offering enhanced sensitivity.

Conclusions:

The developed optomechanical Au/graphene membrane sensor offers superior sensitivity and a broader operational range compared to conventional nanomechanical pressure sensors.
This technology presents a promising platform for high-precision pressure sensing with potential applications in navigation, altitude monitoring, and motion detection.
