Piezo Spirometer: A New Device for the Diagnosis of Pulmonary Failure


Hadi Ghasemifard, Mahdi Ghasemifard, Misagh Ghamari

This study offers a cheap and rapid method for the measuring of breath or measuring the size and capacity of the lung. In this innovative method, the respiration flowmeter than other conventional methods with high costs will be done very fast and accurate. In this device, the measurement accuracy and speed will increase dramatically, because of the high-frequency response than other methods. In this paper, the results of design and manufacturing the spirometry device using nanotechnology are discussed, which including synthesis of piezoelectric ceramics PMNPT and the amplifier circuit design.
