Calibre Breath Metabolic Tracker

Wearable Technologies Design Calibre Breath Metabolic Tracker by Design 1st Calibre is a wearable metabolic tracker that measures breath in real time. Gas and pressure sensors are housed in a small, light wireless module that clips to a face piece. The face piece is made of clear plastic with a soft silicone gasket that rests below the nose. An adjustable head strap holds the face piece in place without limiting breathing or speech. The sensors record airflow, oxygen, carbon dioxide, humidity and temperature. A linked application shows the readings, so the effects of daily activity and exercise on the body can be followed.
