摘要
Mechanically coupled ferroelectric capacitors are surface mounted on a rigid substrate so as to suppress resonant modes of vibration and to limit non-resonant modes of vibrations to those which result in the same polarity output signal. The mechanical vibrations caused in one capacitor (the input capacitor) by an input signal mechanically couples to the other capacitor (the output capacitor) and induces an output signal therein due to the piezoelectric properties of the dielectric. The structure is sandwich-like and consists of a first electrode, a ferroelectric body, a common electrode, a second ferroelectric body and a second electrode. The second electrode is preferably mounted on a rigid substrate.
