ABSTRACT:
Ferroelectric transducers each including two cooperating, identically polarized ferroelectric stacks which are excited in opposite polarity. Each transducer includes a yoke assembly for sensing the respective expansions and contractions of the two ferroelectric stacks, mechanically adding these respective expansions and contractions, and applying the sum thereof to a pair of elongated T-levers, which T-levers serve to displace the output element of the transducer.
