How can we increase the accuracy of the low cost respiration rate measurement devices which are on the market?

Inspired from this Nature paper:

This is an idea which stroke us. We can become g.tec medical ingeneers and make the above device ready for daily use:

But we can also make some preliminar tests with the following setups:

Let us take the Vernier go direct pro:

  • which has an accuracy which has not been validated as far as we know.

Let us take Peter Chartons Respiratory Rate Estimation Toolbox:

  • Which has as far as we know has an accuracy which allows to write in Sensors (Basel). But in which other papers? If we have a device which consists of several devices as in the above Nature paper the accuracy increases.

We have the Inductive Respiration (RIP) Sensor from BIOSIGNALS with the Respiration ADD on:

  • The Inductive Respiration (RIP) Sensor is 800 USD.
  • The Respiration (PZT & RIP) Analysis Add-on is another 500 USD
  • But there is nothing special about the Respiration (RIP) Sensor from BIOSIGNALS. We can find the sensor of the BIOSIGNALS setup for 70 USD (sensor belt ony) on Aliexpress by searching:

«Respiratory Heart Rate Piezoelectric Sensor Nursing Home Hospital Smart Mattress Breathing Belt Sleep Belt»

  • And there are several papers out there which offer algorithms to calculate breathing rate from respiration belts. We do not need to buy a toolbox for 500 USD for it.

Then we can calculate the average breathing rate of these 3 devices, before we become g.tec engineers who continue to develop the above Nature respiration sensor.
