| Summary: | The development of medical study has led to the
improvement of disease detection through breath analysis. The
breath analysis is a study that analyze the volatile organic
compounds (VOCs) in the human exhaled breath which can
lead to the detection of diseases. Current technologies such as
urine and blood test are invasive and painful. Hence, rapid
detection of disease is proposed through breath analysis that is
noninvasive. This work emphasizes on the establishment of
electroacoustic sensor called quartz crystal microbalance
(QCM) sensor. AT-cut quartz was chosen as the piezoelectric
material and aluminum as the electrode. The QCM sensor is
modelled and simulated using the COMSOL Multiphysics to
evaluate the performances in term of resonance frequency,
coupling coefficient and sensitivity. The simulated QCM
sensor with quartz radius of 385 um resonates at 5.109MHz.
The sensitivity of the sensor is 0.8449 MHz/ng after exposed to
acetone gas which act as the breath marker for detection of
diseases in exhaled breath. |
