Hi guys this is from a school assignment in NEMS class.

What type of device could measure blood flow in small blood vessels (sub/millimeter diameter) ?

And why would a cantiliver-like device will clearly not work at the Micro scale for this purpose?

all ideas and thoughts are welcome.

Thank you in advance,

Val

These might be able to help you a bit, or at least I hope they do. I am but a layman so I won't be of much help to you personally.
