Is there any technical detail? I don't understand how it works without cuffs or calibration.

Likely uses pulse transit time and the shape of the pulse wave to infer changes in blood pressure. I wrote a bit about how this works (in the context of Apple Watch's hypertension notifications) here: https://www.empirical.health/blog/apple-watch-blood-pressure...

I took a look at your link ...
It measure blood speed instead of pressure?
How does it transform blood speed to pressure? Doesn't it require a different calibration for each person? Your article says something about deep learning, but IIUC it's to detect unusual peaks in one person.
