Based on a metal-insulator-metal (MIM) waveguide with a side-coupled nanodisk cavity, the sensor using the surface plasmon polaritons (SPPs) refractive index is investigated and studied numerically. The finite-difference time-domain (FDTD) method is used to simulate the performance of the sensor. The numerical simulation result indicates that all the resonance wavelengths in the transmission characteristic...
In this paper, a highly sensitive temperature sensor based on quartz tuning fork resonators is reported. The temperature sensor is configured by ZY (110deg/10deg) Cut quartz crystal wafer based bulk acoustic wave (BAW) tuning fork resonators whose operating frequency is at 31 KHz. The ideal thermo-sensitive ZY cut for quartz tuning fork resonators is analyzed with the theory. The characterization...
A temperature sensing technique taking thermal sensitive quartz tuning fork vibration arm as sensitive components and output of digital frequency is presented. In the design of quartz tuning fork temperature sensor, selecting the cut type of quartz tuning fork according to the each anisotropic nature of quartz tuning fork, so that there is a linear relationship between quartz tuning fork frequency...
A novel high-performance sensor technology for measuring and monitoring temperature is described. This type of temperature sensor using a quartz tuning fork resonator is inherently insensitive to noise because the output is a frequency shift cause by an external temperature. The output can easily be converted into a digital signal and directly connected to a microcontroller without an A-D converter...
