- 摘要：
- Electrohydrodynamic jet (e-jet) printing technology has the capability of sub-micrometer resolution with large-range viscous inks, but is incompatible with nonplanar and insulating substrates. Here, we develop a theoretical model for an electrostatic lens that is incorporated into an e-jet system to shape the electric field inside the printhead. The electrostatic lens can generate electrostatic focusing to drive a Taylor cone for the generation of jetting, without a voltage being applied between the printhead and the substrate, which avoids the influence of standoff height on the nonplanar sub
