Recommended hardware to get the data

Hi! Amazing project, thanks for sharing.

Do you have some recommended smart band or related piece of hardware to measure continuously and extract the raw data?

Hi, the requirement is to have a reliable beat to beat signal (the time between beats, for each beat).
This can be done with any ECG recording device , including commercial chest straps used for sports (such as the polar H7)
Another option is a wrist wearable, which usually are more affected by movement noise but they are less invasive. I didn't tried it for this task but the Scotche Rythm24 record a nice signal. There are less options here because they usually doesn't provide the raw signal
