Electrostatic hydrodynamic jet writing method using electro-rheological fluid and apparatus thereof

摘要

An electrostatic hydrodynamic jet writing method for writing a desired imaged using an electro-rheological fluid is disclosed wherein a writing potential for forming an electric field is applied to a nozzle of an injection head according to a writing signal to vary the viscosity of the ink flowing through the nozzle and to control the flow of the ink. Simultaneously, an accelerating potential is applied between the nozzle and an accelerating electrode on which paper is guided so as to transfer ink of lowered viscosity from the nozzle to the accelerating electrode to perform writing.
