Yes... it was not cheap, exactly :) It was from this company:

Oh, I know there are quartz transducers like accelerometers, pressure and
force gages, etc. from companies like Endevco, Kiag/Krystal, and others.
But in my experience they are lab instruments costing a bundle.
The airbag sensors are cheap... likely a buck or twp. Hence the use of
silicon.

As you feel your heart beat, google for Quartz Pressure Sensor
Again, I think these are semiconductor sensors.
Yes, but there are also quartz pressure sensors. Long time ago I used a
equipment to measure water columns (and hence sea waves height) that
used a quartz-based pressure sensor. It was a very sensitive equipment.
