Popis: | A highly sensitive temperature sensor based on hollow microsphere is demonstrated for ocean temperature measurements. The effect of sensor parameters on temperature sensitivity is investigated with the experiments using different parameters hollow microspheres, tapered fibers with different waist diameters and different kinds of solution. A high sensitivity of 396.70 pm/°C is obtained when the hollow microsphere is filled with ethanol. A high temperature resolution 1.75 × 10-3 °C is obtained when the hollow microsphere is filled with cyclohexane. The volatilization process of 2 μL ethanol is detected to demonstrate good dynamical response of the sensor. |
