Transcript

  • 1. Novel MEMS Respiratory Flow Sensor Respiration activity is commonly monitored clinically to prevent sudden infant death syndrome or to record a patient’s physiological status for sleep studies and sports training]. Various sensors and sensing methods have been developed to measure respiratory rate and/or lung capacity, including the monitoring or measurement of transthoracic impedance, blood O2/CO2 concentration, and breathing airflow among them, breathing airflow measurement is the most direct method, since it measures airflow directly, rather than estimating it by measuring another parameter. Breathing airflow is typically detected by sensing pressure or temperature, and the adopted sensors may be resistive, thermoelectric, pyroelectrical, or piezoelectric. In the present work, a resistive, CMOS-process-compatible flow sensor is proposed. Existing System: Generally the information on respiration should be monitored personally by an expert. The respiratory flow is measured by sensors or any other devices and is noted periodically in patients’ medical file manually. The values are analyzed for abnormality by a medical expert and treatment is given according to that. Proposed System: In this project, MEMS sensor is used for monitoring the respiration flow rate of the patient. This resistive flow sensor was manufactured by the TSMC 0.35 m CMOS/MEMS mixed-signal 2P4M polycide process. The sensor was demonstrated to be sensitive enough to detect the respiratory flow rate, and the relationship between flow rate and sensed voltage is quite linear. If one can integrate the sensor with its sensing circuit into a single chip, the cost of a pneumotach system can be greatly reduced. Moreover, the proposed sensor is useful in both invasive and noninvasive applications.

  • 3. Advantages  Since the measurements are taken automatically, there is low possibility for errors to occur which could avoid fatal.  Erroneous values may not be noted.  Database maintenance may be managed easily. In this case the patient can move onto his work.
