Owingto this advancement, using biosensor/chemical sensor which consists of QTF transducers with features that can takesensitive analyte measurement in picogram level will be able to spread. ![]() As a result, a QTF sensor device was fabricated that has furtheradvanced features when compared with its alternatives and works with a more accurate measurement method. Six other QTF transducer types, 32, 32.768, 40, 65.536, 75, and 100 kHz, havebeen studied as the other novel part of the research. Moreover, the effect of the ambient temperatureduring the measurements was checked. In this study, a novel, low-cost, portable quartz tuning fork sensor devicewith ability to work with any kind of display is presented in detail. When QTF sensor studieswere investigated, it was found that explanations on the details of instrumentation part were limited, and in addition,there was no compact commercial products. This study isundertaken to design and fabricate a sensor device for the measurement of QTF transducers. Since quartz tuning fork (QTF) resonance frequency depends on the mass adsorbed toits prongs, it is generally used to measure minor mass change and detect target analyte in picogram levels. All these research are helpful to design satisfactory performance of the sensor for temperature measurement.Recently, sensor and biosensor applications have become widespread and are now significant tools in thebiomedical field and other areas. The experimental results shown that a temperature accuracy of 0.01 ☌ and a resolution of 0.005 ☌ within temperature range from 0 ☌ to 100 ☌. The whole structure is 500μm thickness, the length of tuning fork arm is 3076μm and the width of tuning fork arm is 600um, the frequency of tuning fork is about 37kHz with a sensitivity of rough 85 ppm/☌. Finite element method is used to analyze the vibratory modes and optimize the structure. Based on this principle, a resonant thermometer is designed. When an external temperature is change, there is a shift in its natural frequency. The quartz tuning fork temperature sensor consists of two prongs connected at one end of crystalline quartz plate with thin-film metal electrodes deposited on the faces, which is used to produce vibration in response to alternating voltages and detecting the resonance frequency in the meantime. The quartz tuning temperature sensor is designed vibrating in flexural mode with a new thermo-sensitive cut. In this paper, a low cost quartz tuning fork temperature sensor adopting H-shaped tuning fork resonator to address miniaturization, high resolution and high stability has been designed, developed and tested. ![]()
