Figure 2. High-brightness, ultrathin, and flexible thermosensing patches for in situ temperature monitoring. a Schematic of the real-scene monitoring under 980 nm excitation. b Photographs showing the lateral size, thickness, and bendability of the high-brightness flexible ultrathin microscale thermosensing patches (HFMTPs), demonstrating conformal contact with both flat and curved substrates. c Images of the ultra-bright luminescence of the HFMTP under 980 nm irradiation and demonstration of in situ temperature measurement. d LIR-derived temperature fluctuations under distinct operating conditions: argon flow (Ar-NoStir), vacuum (Vac-NoStir), argon flow with 20 rpm stirring (Ar-Stir), vacuum with 20 rpm stirring (Vac-Stir), and argon flow with 100 rpm stirring (Ar-FastStir). The temperature controller remained active throughout. e Statistical analysis of the deviations between LIR-derived and thermocouple-measured temperatures. f Repeatability of the LIR readout over five heating and cooling cycles between 373 and 423 K.
