Wait, this looks very nifty. But digital blood pressure monitor with air pump is quite cheap nowadays and very easy to get one.
Also this seems to be the extension of measuring heartbeat with camera + flashlight that was out there like 10 years ago (you measure it by placing your thumb over your phone's camera). I wonder if eventually smartphone maker would just have it built in.
