That's the right idea, but it's the other way around.  The harder 
you press on them the less the resistance.

You get a quick drop in resistance and quick recovery.  It's not 
sluggish like I thought it might be.  That resistance change can be 
converted to a voltage spike, similar to what a piezo produces, but 
without the "ringing".  Does that make sense?  There's a circuit in 
the FSR pdf from earlier in the thread (page 23?) that produces a 
voltage trigger.  That would be a good starting point.
