A high-sensitivity and miniature open cavity Fabry–Perot interferometer (OCFPI) encapsulated with the polydimethylsiloxane (PDMS) film based on high-order harmonic Vernier effect is designed experimentally investigated. To best of our knowledge, PDMS applied for first time to fill OCFPI obtain high-temperature sensitivity. The resonant dip (peak) wavelength temperature sensor monotonically move...

Abstract A high-sensitivity temperature sensor based on the harmonic Vernier effect is proposed and verified by experiments. The main component of a Sagnac interferometer consisting two sections polarization maintaining fibers (PMFs) spliced with an intersection angle 45° between their fast axes. achieved setting length one PMFs integral multiple ( i -times) other plus detuning factor. Compared...

Abstract Flexible temperature sensors have been extensively investigated due to their prospect of wide application in various flexible electronic products. However, most the current only work well a narrow range, with at high or low temperatures still being big challenge. This proposes thermocouple sensor based on aerogel blanket substrate, temperature-sensitive layer which uses screen-printing...

Abstract To study the correlation between cooling load and air temperature, this paper uses maximum comparison method to calculate based on actual data of power grid, temperature correction model correct daily then establishes a high-order regression corrected temperature. The is applied sensitivity analysis in Chongqing grid sub-regions, corresponding change law obtained, which provides an imp...
