Student asked John Melville this question. The sensor is demonstrated at 32 minutes in the following Vernier demonstration video:
We tested the device and found, that it continued to output sensor data even when it was removed from the chest. We suppose that this is due to the fact that the device calculates a rate, eventually from a moving average. We are interested in the device to measure respiration rate during breath meditation.
In the graphs of Vernier, we can see how the respiraton rate decays if the subject does not breath, sometimes slower, sometimes faster. John Melville from Vernier says it is not a device which was developed for clinical applications. But it is one of the view devices which shows respiration rate in real-time, and it is easy to handle. And devices which measure and calculate respiration rate with a sensor belt are usally very expensive.
What it can be used for depends on how accurate it is. The accuracy can be tested by counting the number of breath we take in a minute manually and compare it to the data of the Vernier respiration monitor.
Respiration rate cannot be measured with this device while running. But there is a paper which calculates the respiration rate from a Polar H10 chest strap from the Swiss Federal Insitute of Technology in Lausanne while running. You can find the link to it in our journal.
