ABSTRACT:
With a piezoelectric transformer formed of a ferroelectric element which generates a high voltage in a secondary section upon application of an AC voltage to a primary section, ground electrodes are attached to upper and lower surfaces of the secondary section of the piezoelectric transformer via a dielectric sheet for insulation in tight contact therewith such that a dielectric barrier discharge occurs around the ground electrodes to generate positive and negative ions, and an air flow is injected from an air nozzle to flow toward a neutralized subject across the ground electrodes.
