Aktiia has a product on the market which supposedly already does this https://aktiia.com/uk/. It is based on an optical method though.

A year or two ago, I interviewed a developer who worked for one of the companies trying to build these types of optical blood pressure sensors. I have high blood pressure so I was keen to learn more. The gist of his message was that even in excellent conditions, it was very inaccurate.

I wonder if things changed by now.

The Aktiia bracelet takes measurements automatically but not continuously. It produces about 1 measurement point every hour.
