Peter Gamma from www.petergamma.org studied for many years physiological multi-sensor devices up to 50 000 USD:
These devices are expensive and are often rarely used. They are not optimized for low-cost high-quality.
Neurokit 2 offers five physiological channels which makes it very interesting:

- But for physiologists 3 channel ECG devices are the gold standard
- And PPG devices are hardly used, since they are not very accurate
- For the measurement of respiration rate, Neurokit 2 uses devices like respiration belts. But after studying such devices to measure respiration rate, we came to the conlcusion that spirometers are the most accurate devices to measure respiration rate. Spirometers are used by companies such as iWorx and Schiller medical. Spirometers can be used with Neurokit 2. But the data have to be imported manually.
- Physiological multi-sensor devices are very expensive. But there is a lot which could be optimized with those.
- A combination with several devices could be interesting for physiologists, for instance a combination of Neurokit 2 with OpenBCI 16 channels to get more channels?
- Since physiological multi-sensor devices are so expensive, every channel and every coder is very precious.
- And a combination of several devices could be very interesting.
Neurokit 2 seem to have good programmers with good coding kills. But do they not lack the physiologists who are good critics of this device?
