Abstracts
Droplet generation by electrohydrodynamic (EHD) spraying has advantages in monodispersity and small size
regardless of the nozzle diameter. In this research, we investigated formation and variation of printed patterns
formed by the EHD spraying using the ceramic suspension. The pattern lines were formed through cone-jet mode
which was one of modes of EHD spraying. The onset voltages at which the cone-jet was achieved and the widths
of the ceramic patterns varied with the changes of the flow rates and the diameters of ground electrodes. Under the
condition of fixed flow rate and diameter of ground electrode, the widths of patterned lines increased with the
increment of applied voltages. As we increased the flow rates (1, 5, 10 ¥ìL/min) and the diameters of ground
electrode (1, 100, 1,000 ¥ìm), widths of patterned line and threshold voltages increased. The differences in width
were not as large as those of other conditions.
