How does it work?

Fitted inside the Belt is an inflatable air bladder, which is moulded to two rubber tubes. One of these tubes has a hand pump bulb that is used to inflate the air bladder, the other tube is used attached to a Differential Gas Pressure Sensor to monitor the change in pressure as the test subjects chest expands and contracts during breathing

Breathing Patterns

The Breathing belt is placed around the lower chest. The bladder in the belt is connected to a Pressure sensor and lightly pressurised. Changes in chest size due to breathing will create a change in pressure in the bladder, which in turn will be recorded by the sensor.
