TitleDENSITY MEASUREMENT PERFORMANCE IN FLOWING LIQUID USING MICROCANTILEVER-BASED RESONATORS UNDER BENDING AND TORSION VIBRATIONS

AuthorLinya Huang, Libo Zhao, Yingjie Hu, Hongyan Wang, Dejiang Lu, Xudong Fang, Guoxi Luo, Chenying Wang, Ping Yang, Weixuan Jing, Yulong Zhao, and Zhuangde Jiang.

AbstractThe performance of microcantilever-based resonator working under different operation modes is analyzed in fluid density determination at different flow velocities. A setup is designed to control the liquid flow velocity along normal and tangential directions in the range of 0-4.37 m/s. Microcantilever-based resonators are fabricated with different lengths, which are excited to vibrate under 1st bending and 2nd torsion modes. The experimental results show that the normal flow velocity plays a leading role to impair the density measuring accuracy. The microcantilever-based resonator with shorter length and in higher order vibration mode is demonstrated to have a better measurement performance in flowing liquids.


TitleLUMPED ELEMENT MODEL FOR CMUTS-BASED BIOCHEMICAL RESONANT SENSOR

AbstractLumped element model (LEM) for resonant chemical sensors based on the capacitive micromachined ultrasonic transducers (CMUTs) was developed and analyzed with electrical characterization. The CMUTs chip were functionalized with the electrospinning technology. Two Butterworth Van-Dyke (BvD) models for functionalized CMUTs were proposed and analyzed with different DC voltages. Considering the electrical phase with parasitic capacitance, the modified BvD model can be used to illustrate more comprehensive features for both mechanical impedance and phase properties. The parallel capacitance was measured accurately using an impedance analyzer, and the quality factor was calculated based on the proposed model under different DC voltages. These models will provide important theoretical basis for CMUTs-based chemical sensors to further electrical analysis and oscillator design.
