Sensors and method for defining breathing signatures for identifying respiratory disease

A method of obtaining lung function parameters comprising forced vital capacity (FVC), forced expiratory volume in one second (FEV1), tidal volume, vital capacity, maximal mid expiratory flow (MMEFR), forced expiratory flow (FEF25-75), or forced vital capacity in a subject comprising:

• placing a plurality of motion sensing devices on the subject at the right pectoral region, a right hypochondrium region and a sternum, respectively, of the subject, each motion sensing device of the plurality of motion sensing devices comprising at least one accelerometer, at least one gyroscope, a battery, a processor, and a wireless transmitter, the processor configured to read motion data from the at least one accelerometer and the at least one gyroscope and to transmit the motion data over the wireless transmitter;
• placing at least two electronic cameras in a position to provide stereo images of a chest and abdomen of the subject;
• collecting the motion data from the plurality of motion sensing devices with a digital radio;
• constructing a three-dimensional surface model of subject using three-dimensional surface model extraction routines on stereo image pairs from the at least two electronic cameras after the subject's inhaling but prior to exhaling, after one second of exhaling, and after complete exhalation by the subject;
• and
• analyzing the collected motion data and the three-dimensional model together to determine lung function parameters comprising FVC, FEV1, tidal volume, vital capacity, maximal mid expiratory flow (MMEFR), forced expiratory flow (FEF25-75), or forced vital capacity.
