We are interested in breath rate, since we are interested in breath mediation. We used a Garmin Fenix 6 for this purpose. But we found that the breath rate on these watches is very inaccurate, and therefore not very helpful. Are there any physiological data on sports watches which are helpful for scientific purposes at all?
An alternative is Peter Charlton Respiratory Rate Estimation Matlab toolbox. It has been downloaded about 3000 times to this date. But this does this mean that it is used also in scientific papers.
What is helpful that the respiratory rate estimation project allows calibration of respiration data. This is very difficult with the Garmin Fenix 6.
If we look at Peter Charltons papers:

The document which stroke us the most in this context is Peter Charltons PhD. thesis about this topic. After a first look, none of his papers stroke us. Is respiratory rate estimation used in clinics and hospitals? Or is it only possible in theory? We did not study this in detail yet. What we found helpful is the documentation about the respiratory rate estimation project:

We know of papers of the Swiss Federal Institute of Technology in Lausanne who uses respiratory rate estimation. The link to the paper can be found in our journal. They do it with a Polar H10 chest strap. But we did not study this paper yet. Is it based on Peter Charltons respiratory rate project?
Is respiratory rate estimation widely used? We do know little about it. Respiratory rate measurement seems to be still a topic which is interesting for device developers, we can find that there are many papers about it, and many methods are used. And we do not know of a winning method for respiratory rate.
