Unless you count gravity waves, most of us consider gravity to be a
unchanging acceleration. So, yes, I guess I did mean to say that
piezoelectric accelerometers don't respond to gravity. ;-)  And, no, I don't
want to start a thread about gravitational interactions between the earth
and moon or other celestial bodies either....

I think he really meant that the piezo ones do not provide a DC voltage out
for a non changing acceleration.
