“…Special nozzle setups such as those that involve the insertion of a nonconductive fi ber inside the nozzle may be used to improve the stabilization of jets by reducing the backfl ow in the meniscus due to the tangential electrical stress. [ 66,67 ] Techniques for visualizing the jetting behavior during printing can be valuable both to research on the fundamental mechanisms and to process control. High-speed cameras and specialized optics are often used to achieve the required spatial and temporal resolution, although the fi nest nozzle tips and the smallest droplet sizes cannot be resolved by optical methods.…”

“…Stachewicz et al found that, besides the size of the meniscus and droplets, electrohydrodynamic behavior during printing can be affected by the presence of the hydrophobic coating. Special nozzle setups such as those that involve the insertion of a nonconductive fiber inside the nozzle may be used to improve the stabilization of jets by reducing the backflow in the meniscus due to the tangential electrical stress …”

This review gives an overview of techniques used for high-resolution jet printing that rely on electrohydrodynamically induced flows. Such methods enable the direct, additive patterning of materials with a resolution that can extend below 100 nm to provide unique opportunities not only in scientific studies but also in a range of applications that includes printed electronics, tissue engineering, and photonic and plasmonic devices. Following a brief historical perspective, this review presents descriptions of the underlying processes involved in the formation of liquid cones and jets to establish critical factors in the printing process. Different printing systems that share similar principles are then described, along with key advances that have been made in the last decade. Capabilities in terms of printable materials and levels of resolution are reviewed, with a strong emphasis on areas of potential application.

“…When the electrical force is stronger than the surface tension force, a fine droplet or jet may be generated on the apex of the cone [4,5]. The diameter size of the droplet or jet from the cone is 10-1000 times smaller than the size of the nozzle diameter [6][7][8]. Droplet ejection could also be controlled to implement a dropon-demand operation [9][10][11][12].…”

Invisible Ag mesh transparent electrodes (TEs), with a width of 7 μm, were prepared on a curved glass surface by electrohydrodynamic (EHD) jet printing. With a 100 μm pitch, the EHD jet printed the Ag mesh on the convex glass which had a sheet resistance of 1.49 Ω/□. The printing speed was 30 cm s−1 using Ag ink, which had a 10 000 cPs viscosity and a 70 wt% Ag nanoparticle concentration. We further showed the performance of a 3-D transparent heater using the Ag mesh transparent electrode. The EHD jet printed an invisible Ag grid transparent electrode with good electrical and optical properties with promising applications on printed optoelectronic devices.

“…1986, Hayati et al researched the backflow at the center of cone jet, and a inserted non-conductive probe in the spinneret is introduced to inhibit the backflow and reduce the required voltage [8]. Back flow in meniscus is eliminated by the inserted probe, then the printing solution flow along the probe and jet is formatted from the probe tip, which provides a good way to control the motion track of jet motion [9]. But electrical field strength around the nozzle was not increased by the inserted non-conductive probe.…”

Stability jet ejection and precision deposition are the two keys for industrial application of electrohydrodynamic printing. In this paper, inserted conductive probe is utilized to gain stability jet, which would increase the electrical field strength, reduce the back flow, onset and sustaining voltage. Lower applied voltage would enhance the stability of electrospun jet, in which fine jet can be used to direct-write orderly Micro/Nano-structure. With the guidance and constrain of inserted probe, the oscillating angle range of electrohydrodynamic jet is decreased to 3°from 15°, and the width of printed structures is 21μm in average that is much narrower than that printed from spinneret without probe (74μm in average). Spinneret with tip provides a good way to improve the control level of electrohydrodynamic printing, which would accelerate the industrial application of electrohydrodynamic printed Micro/Nano structure.
