Why are there only scientific papers with ECG & InfluxDB, but hardly any with EEG & Influx DB?

Home Assistant with the Apple watch shows us an example of a physiological multi-sensor device:

We can find papers which use ECG with InfluxDB, as for instance this one:

ECG Data Visualization: Combining the power of Grafana and InfluxDB

https://ieeexplore.ieee.org/document/10104857

We found also a paper which uses EEG with InfluxDB, as for instance this one:

https://ieeexplore.ieee.org/abstract/document/9087877

But the EEG devices it uses are for instance the Epoc Emotiv Flex 32, and the devices Dr. Cody Rall
used years ago from Emotiv:

But where can we find papers whith 256 channel EEG devices and InfluxDB?

If we look for new 32 channel EEG devices which are based on InfluxDB, we find the old ones:

But were are new implementations based on TGAM, A/D converters & InfluxDB, as we would expect for instance from these instructions?:

Why does Peter Gamma from www.petergamma.org not find an affordable EEG device which is based on the ADS1299 altough he is looking for it since years & years & years?

To join all of these sensor data into one InfluxDB, all channels need to be sampled at exactly the same time. Can this for instance not be done with 4 Rasperry Pi’s with 4 PiEEGs which are samplet at exactly the same time:

But to sample all EEG data from individual TGAM modules would require aditionally devices which sample all the channels at exactly the same time.
