Abstract
A sensor capable of detecting both airflow in spirometry and a full range of sound frequencies is provided. The airflow sensor includes a movable flap with one or more integrated strain gauges for measuring displacement and vibration. The sensor may be a bidirectional elastic flap airflow sensor that is capable of providing data needed for both spirometry and auscultation measurements. The sensor is provided in connection with a software module that analyzes sensor output waveforms and provides for correction functions that correct for certain non linear response functions of the flap. The correction functions are also suitable for non medical fluid flow metering applications. Additional devices may also be affixed to the flap such as sensors for the ambient level of various chemicals sensors for temperature sensors for humidity and microphones.
