💡 Novelty & Significance:
The novelty lies in a partial-inner-cladding optical fiber that suppresses photothermal artifacts by isolating the sensing layer from the self-heating coupling interface. This extends excitation power tolerance and signal-to-noise ratio, achieving record accuracy (0.104°C), precision (0.05°C), and resolution (0.2°C). It enables reliable battery thermal warning and in situ Bárány caloric test diagnostics.
