I am in master course. My major is Mechanical engineering in Korea, so
I have few materials about Mems; pressure sensors.  But now I'm
researching into process for making micro pressure sensors.  I am
looking for a variety of MEMS sensors and product process that are out
of the R&D stage and are being produced and sold. Specifically, I need
a large quantity of pressure sensors.  Any help would be appreciated.

Thank you.
