Abstract
In described examples, each node between adjacent capacitive elements of a stack of series-coupled capacitive elements is biased during a reset mode, where each of the capacitive elements includes piezoelectric material. A strain-induced voltage is generated across each of the capacitive elements. Each of the strain-induced voltages is combined to generate a piezoelectric-responsive output signal during a sensing mode at a time different from the time of the reset mode.
