Aiming at the achievement of temperature measurement with high sensitivity in the sub-wavelength scale, an all-metal meta-surface (AMMS)-based sensor is numerically demonstrated. Based on the sharp plasmonic resonances and the simultaneous use of perfect absorption response, temperature sensing with an ultra-high enhancement factor of 263 for the spectral figure of merit (FOM) factor is obtained in comparison with that of the common plasmonic sensors. Moreover, spectral shift-related sensitivity S is up to 0.274 nm/°C. These sensing properties indicate the designed sensor can play a significant role in optoelectronic devices for high-integrated and high signal-to-noise ratio temperature detection.
