Application of a microsphere-based fiber-optic sensor with 200 nm zinc oxide (ZnO) coating, deposited by Atomic Layer Deposition (ALD) method, for temperature measurements of supercapasitor, is presented. Internal temperature of the supercapacitor is investigated in the range between 30°C and 90°C. The supercapacitor temperature was investigated using interferometric setup consisting of broad band light source with a central wavelength of 1310 ±10 nm (SLD-1310-18-W, FiberLabs Inc., Fujimi), which generates an optical signal.During the measurements, the integrity of the sensor head can be simultaneously controlled. The study shows the temperature of supercapacitor can be successfully monitored by embedding the microsphere-based sensor inside the capacitor. |
