Abstract

Observation of electrostatic droplet ejection was described using planar needle inkjet. Electrostatic droplet ejection from the planar needle head was directly observed with a high-speed camera equipped with a high magnification optical system. It was found that the width of needle and microchannels were 45μm and 110 μm respectively. Electrostatic ejection of droplets were observed to continue when a voltage of 5 kV was applied between the liquid and an counter electrode, which was about 50μm apart from the tip of needle head. The results expected in assisting explication of the phenomena using the 3-dimensional corn-shaped needle configurations.
