Respiration measurement

Finally i did a more extensive research for my main interactive project at LCC, monitoring breathing of many people resp. hearing a building breathe.

These are methods of measuring (human) respiration in the most general sense:

With touch

1. Mouth airflow
by Spirometer

2. Nasal temperature probe
by thermistor

3. Acoustic
by stethoscope

4. Thoracic (chest) or abdominal (belly) expansion
by strap extension (e.g. using ultrasonic distance measurement)


1. Acoustic
by ceiling dome microphone

2. Thermal
by infrared imaging

3. Capnographic
by measuring exhaled carbon dioxide
