Biosensor SIgnal Data HRV, EDA/GSR, EEG

In one of your youtube videos you mentioned a canonical use of TinyML Edge Impulse with Biosensor Data, even showing a cat with EEG headgear. What have you done or published about biosensor data and do you have any plans for interfacing with a board like bitalino or working with commercial maker’s biosensors?

Hi @laefsky, we’re doing a variety of things with biosignal data, including HRV analysis, but this is done with our customers so we don’t share these algorithms.

It’s however very doable to send raw PPG data into Edge Impulse (I’ve done some initial testing with the, and then adding a processing block that extracts HRV features from the signal (processing blocks), then feed that data into a classifier.
