Electrohydrodynamic Printing Head Capable of Drop-On-Demand Printing And Manufacturing Method Thereof

摘要

The present invention provides a drop-on-demand (drop on demand) electric hydraulic drive system and the printing head relates to a method of manufacturing the same. More particularly, the present invention provides a printing head that can be patterned based on the electrostatic force, a hole for supplying the fluid to the printing head (20); An electric hydraulic fluid containing conductive particles (electrohydrodynamic) is sprayed by a pressure nozzle (21); The hole 20 and the nozzle 20 connects the channel 22, the main body 23 formed on the inside; The channel 22 is formed inside the nozzle 21, the meniscus of the fluid at the nozzle located in the upper column controlling the actuator (meniscus) (thermal actuator) that acts as micro-heater (24); And is formed in the nozzle (21) electrode (25) to form an electric field for an electric hydraulic spraying; drop containing the-on-demand (drop on demand) is for the printing head of the electric hydraulic drive system.
