ABSTRACT The continuous bipolar mechanical output of a nonrectifying transducer is synthesized when the electrical segments 2 of a rectifying transducer are alternately switched into and out of a resonant loop in synchronism with polarity changes of the alternating drive signal. The known extraordinary transduction efficacy of a diverse class of rectifying transducer materials is thereby advantageously applied, while the known high electrical efficiency of resonance is also applied. Continuous bipolar transduction provides essential ingredients for the synthesis of nonsinusoidal mechanical output waveforms that afford extraordinary mechanical efficiency in a growing class of mechanical actuators, such as forcers, positioners and rubless walkers. Electrical resonance, in combination with nonsinusoidal mechanical waveforms, therefore provide a segmented rectifying transducer drive system of extraordinary efficacy. 91R018
