The temperature drift suppression of mode-localized resonant sensors

This paper for the first time experimentally demonstrates the temperature drift suppression in the linear measurement range of mode-localized resonant sensors. Based on a mode-localized stiffness sensor, within a temperature range of [290, 350] K with a step of 10 K, the maximum measurement error of the amplitude ratios readout is only 8.9%, while that of frequency shift is 1137%. And the shift of the scale factor of amplitude ratios is only ∼11.6% whereas that of the frequency readout is ∼61.6%, which verifies that mode-localized sensors own an excellent capability of temperature drift suppression.
