1. In many varying-gap capacitive sensors with a large capacitive electrode, we often perforate the capacitance plate in order to:

a) Reduce intrinsic stress in the material making the capacitor

b) Improve capacitive sensitivity

c) Improve bandwidth

d) Reduce pull-in voltage

2. If you are asked to choose the spring design for an accelerometer that provides the best performance in terms of occupied area, tolerance to stress, and overall sensitivity, which design would you choose:

a) Cantilever design

b) Crab-leg design

c) Folded-beam design

d) Straight bridge design
