“…Thus, it is advisable to conduct a study on the vertical integration of a thermomechanical capacitive temperature converter with a microelectronic element, which changes its output signal in the deformation of the input electrode. Such solutions will allow not only contact measurements of temperature, but also the use of sensors, as shown in [11], to record thermal effects of radiation.…”

“…According to Sun et al [17], an optical fiber temperature sensor based on temperature cross sensitivity with a RI sensitive device had an improved sensitivity of 350 pm/°C. Rahman et al [18] have demonstrated bimetallic layer fiber optic temperature sensor and showed moderate temperature sensitivity. Nevertheless, these sensors have their own limitations, such as design complexity, low resolution, poor sensitivity, non-linearity, and dynamic range.…”

Recently, the performance of solar cell is impacted by rising panel temperatures. For solar cells to work at their best and have the longest possible useful life, the temperature of the panels must be kept at an ideal level. Current temperature sensors have a slow response time, poor accuracy, and low resolution. Meanwhile, Al2O3 and its derivatives have demonstrated a noteworthy role in temperature sensing applications due to its greater surface area, ease of synthesis, tailored optical characteristics, high melting point, and high thermal expansion coefficient. Al2O3-based nanoparticles have been employed in fiber optic-based temperature sensors as a sensing layer, a sensitivity improvement material, and a sensing matrix material. In this chapter, we discuss the function of Al2O3-based nanomaterials in evanescent wave-based temperature sensors, sensing characteristics such as sensitivity, linearity, and repeatability. The ZAZ-based sensor (Section 3.1) shows an operating temperature range between 100.9°C and 1111.0°C, the temperature sensitivity becomes 1.8 × 10−5/°C. The fabricated sensor had a linearity of 99.79%. The synthesized Al2O3 nanoparticles (Section 3.2) were given better linearity and high sensitivity (~27) at 697 nm compared with other sensing materials such as ZnO, SnO2, TiO2. The Al2O3-MgO (50–50%) (Section 3.3) demonstrated an ultrahigh sensitivity of 0.62%/°C with a better linear regression coefficient of 95%. The present advances and problems are also discussed in detail.
