✦ Synopsis

Pure circuit models of transducers have been used for many years with varying degrees of success. However, pure circuit models impose restrictions not all of which are predicated on laws of physics. These restrictions can produce transducer models which are nonphysical. Bond graph models ofSeer an alternative that is less restrictive and thus better able to provide clear physical insight. We discuss the problem of pure circuit models of transducers and the advantages of bond graph approaches by examination of the special case of a piezoelectric transducer.
