Abstract
A dryer includes a plurality of piezoelectric transducers in electrical communication with a high frequency piezoelectric oscillation generator. The piezoelectric oscillation generator controls the duty cycle and resonant frequency source signal that drive the plurality of piezoelectric transducers non-continuously. The piezoelectric transducers dry the wet articles without heating air passing through the articles.
