I did a little design calculation based on the 25 Hz upper frequency response of
the sensor.
The resonant frequency of the sensor needs to be above 25 Hz. So to see what
ball park we are in I calculated the 1 g deflection of the mass with a resonant
frequency of 30 Hz. This works out to be 0.275 mm.  This gives a total
deflection of 0.55 mm at 2 g. This is not much. We could get away with a simple
cantilever beam design or thin solid metal disks for the spring.
