How do the Blood Pressure Meter on Indiegogo work?

Hello,

Today I was surfing a little on the Indiegogo website and found two projects that claim to measure blood pressure. I did see electronic blood pressure meter, but they always had a mechanical moving part. The projects on Indiegogo are as small as a watch and it looks like they don't have any mechanical moving parts. So I was wondering how this meters work and if someone has any documentation? Are thees project legit?

Thanks

This one uses the small capillary pulsations in your fingertip which the accelerometer IC measures and converts to BP.

NASA used to measure the timing blood wave along an astronauts arm artery as a non-invasive flight watch, but it had to be calibrated to the individual.

I don't know about the blood glucose but the H2 is not approved where I live. I have high blood pressure and I use the omron monitor hey claim is hard to use and it is easy to work as far as I am concerned.

So I think it is just hype.
