Abstract:

The objective of the project was to examine if it was possible to develop a low-cost temperature sensor using dual fiber Bragg gratings (FBGs). The intention was to use one FBG as a reference and let the other FBG function as the sensor. The study shows that it is possible to characterize the temperature sensitivity of each FBG and use the reference to sweep over the applicable spectrum to find the Bragg-wavelength of the sensor. This could be done measuring only the total intensity instead of intensity per wavelength with an optical spectrum analyzer, and with high accuracy. Thus, it seems fe

Abstract:

This dissertation proposes a miniaturized optical fiber based sensor system for the measurement of 3-dimensional vector magnetic fields. The operation of the sensor system is based on the detection of magnetostrictive dimensional changes in the sensor gage using a modified extrinsic Fabry-Perot Interferometer configuration. Because of the magnetostrictive reflector the gap length depends on the magnetic fields applied to the sensor. Since the diameter of the magnetostrictive sensor gage is 125 micrometer which is the same as that of the input/output fiber, the sensor is simply constructed b

Abstract:

Among various nanofillers, carbon nanotubes (CNTs) have attracted a significant attention due to their excellent physical properties. Incorporation of a very low amount of CNTs in polymer matrices enhances mechanical, thermal and optical properties of conductive polymer nanocomposites (CPNs) tremendously. For mechanical sensors, the piezoresistive property of CNTs/polymer nanocomposites exhibits a great potential for the realization of stable, sensitive, tunable and cost-effective strain sensors. Achieving homogeneous CNTs dispersion within the polymer matrices, understanding their complex pie

Abstract:

The temperature sensor design discussed in this thesis, is meant mainly to monitor temperature at power outlets. Current variations in power cords have a direct impact on the surrounding temperature. Sensing these variations ,enables us to take necessary measures to prevent any hazards due to temperature rise. Thus, for this application we require a sensor with a moderate temperature error (_10C) over a sensing range of -200C to 1500C. Low power consumption and simple digitizing scheme alleviate measurement errors due to self heating effects of the sensor. A current starved inverter based r

Abstract:

碩士<br>國立臺灣科技大學<br>電子工程系<br>105<br>This thesis elaborates on different methods to accurately measure absolute temperature using CMOS integrated circuits, and to provide output value in a robust and easy to use manner. Proposed circuit comprises of a temperature sensitive relaxation oscillator, a reference oscillator and a counter. Output data are provided in plain binary format. The design is implemented using TSMC 0.25 m mixed-mode process. Both pre-simulation and post-simulation results prove the correctness of this approach. Post-layout simulation shows errors of ±1.5 °C across temperature
