Respiration rate is one of the key parameters for meditators. The physiological range of the respiration rate to be normal is from 12 to 20 breath per minute, according to Peter H. Charlton, developer of the Matlab Toolbox for respiratory rate. But which devices can be used to write paper in the journal «Nature» to measure respiratory rate?
Peter Gamma from www.petergamma.org prefers devices which can be used for writing papers in Nature, since he is a really serious physiologist from Switzerland. The following paper shows an example of a device to measure respiration rate which was published in Nature:
«Wearable radio-frequency sensing of respiratory rate, respiratory volume, and heart rate»
which was publised Published: 28 July 2020:
https://www.nature.com/articles/s41746-020-0307-6
The device which was used in the Nature paper looks like this:
It uses a combination of:
- respiratory rate estimation
- measure air flow
- respiration belt
- RF sensor (RF, for radio frequency, is in electrical engineering the name for frequencies above those of audible sound waves).
- NCS sensor: the Non-Contacting Position Sensor (NCS sensor) consists of a molded sensor housing and is used instead of the built-in potentiometer in applications with the following process conditions: Strong vibration and shock loads (oscillations) on actuators and process valves.
Devices like this seem not be developed well, and especially this device looks like a device which is not yet developed for daily use. But it is a device which is very helpful what might be the optimum to develop such a device for daily use. Devices which currently are available on the market to measure respiration rate for research applications cost more than 1 000 USD.
