EEG, ECG, MEG devices can be very expensive, as we can see in the following comparison table:
A g.tec medical EEG device with 32 channels costs around 50`000. With OpenBCI components, we think it is possible to build EEG devices which are much cheaper, especially if combined with InfluxDB.
OpenBCI is not designed to work with InfluxDB, for instance if we want to combine muliple modules in an array to reduce costs. A hardware change would be necessary for this.
Eventually, manufacturers of EEG research or medical grade EEG devices are not interested in such OpenBCI devices which are developed to work with InfluxDB to reduce costs, but we are.
We think an update of the OpenBCI modules to work with InfluxDB does not require a big update of the modules, but would make them usable for new applications like InfluxDB.
We think only a cache module component would be sufficient to be added to the OpenBCI Cyton modules. But this question should be answered by engineers who are experts in this field, and not by us. But don t ask an engineer who is only interested in keeping the prices high for EEG devices, ask another one.
