To
transduce is to
induce as a result
of being
induced.
Absorbing one form
of energy and carrying that
energy possibly across a
barrier (such a barrier could be a
impermiable chemical
or
physical membrane) This energy this then
radiated
in it's new form (
mechanical for instance.)
An
ultrasonic transducer for example, carries
electrical
energy into the ultrasonic mechanical
motion spectrum.
Motors,
microphones,
speakers, are also transducers.
