“…[68] Graphene has also been a research focus for the fabrication of electrodes because of its characteristics such as high electrical mobility, thermal conductivity, and mechanical strength in recent years. [66,[69][70][71] Researchers have reported the electrodes made of graphene only, graphene mixed with other carbon materials, or graphene accompanied by platinum (Pt) which was fabricated by e-jet printing. In detail, Wang et al achieved graphene micro-scale structures by e-jet printing ethyl cellulose or Nafion dispersed graphene ink.…”

“…It means graphene enlarged the reaction area and enhanced electronic conduction which made the electrochemical reaction easier. [70] Zhao et al directly wrote graphene layer precisely on the Pt microelectrodes to form graphene/Pt composite microelectrodes by e-jet printing. The graphene did improve the electrochemical response of Pt microelectrodes.…”

Electrohydrodynamic jet (e‐jet) printing technology overcomes some limitations such as the viscosity and resolution of the traditional ink‐jet printing by breaking surface tension of the droplets with high voltage and the formation of Taylor cone. The technique is becoming more and more popular because it can be widely used in the fabrication of the conductive line of electronics, electrode, transistor, sensor, and other electronics as microelectrode, microlen, and heater. This review provides insight into the effect of the influence factors such as voltage, speed, nozzle, jetting ink characteristics, and the representative conductive materials of the ink as metal nanoparticles (NPs) and carbon materials, or organic conductive polymers on the fabrication of the different electronics by the e‐jet printing technology. Specially, the characteristics of different resultant electronics are compared and the possible mechanisms are analyzed. Finally, the challenge and development trend of the e‐jet printing technology are discussed, which will shed a light on the fabrication of the next‐generation flexible electronics with better performance.

“…[21,22] For example, e-jet printing has been used to pattern thin films via lift-off, masked etching, and area-selective deposition. [9,[23][24][25][26][27] However, lift-off-based processes are restricted in the thermal and chemical processing conditions of the overlying film, which must be compatible with the printed "resist" material. Alternatively, while printed features could be used as etch masks for subsequent wet or dry etch processes, the etch compatibility of the printed material restricts the processability.…”

As an alternative to traditional photolithography, printing processes are widely explored for the patterning of customizable devices. However, to date, the majority of high‐resolution printing processes for functional nanomaterials are additive in nature. To complement additive printing, there is a need for subtractive processes, where the printed ink results in material removal, rather than addition. In this study, a new subtractive patterning approach that uses electrohydrodynamic‐jet (e‐jet) printing of acid‐based inks to etch nanoscale zinc oxide (ZnO) thin films deposited using atomic layer deposition (ALD) is introduced. By tuning the printing parameters, the depth and linewidth of the subtracted features can be tuned, with a minimum linewidth of 11 µm and a tunable channel depth with ≈5 nm resolution. Furthermore, by tuning the ink composition, the volatility and viscosity of the ink can be adjusted, resulting in variable spreading and dissolution dynamics at the solution/film interface. In the future, acid‐based subtractive patterning using e‐jet printing can be used for rapid prototyping or customizable manufacturing of functional devices on a range of substrates with nanoscale precision.

“…EHD patterning focuses on the deformation of the liquid film induced by a large-size electrode. A variety of applications are possible such as the fabrication of microlens array, , adhesive array, , and micro- or nanostructures. , EHD jetting focuses more on the multiple jet breakup modes like dripping, whipping, and atomization, , and diversifies the applications like EHD printing, , electroatomization, etc. Moreover, the fine control of the meniscus at the nozzle will result in droplets smaller than the nozzle diameter .…”

In transfer printing, the loaded droplet on the probe has a significant influence on the dispensing resolution. A suitable loading approach for a high-viscous liquid is highly required. Herein, a novel electrostatic loading method is presented, in which the main aim is to control precisely the formation and breaking of a cone-shaped liquid bridge. An experimental device is developed. The influence of electrical and geometric parameters on the feature size of the liquid bridge is investigated in detail. In the formation of the liquid bridge, the increase of voltage or the decrease of the air gap can enhance the electric field intensity, thus reducing the formation period and increasing the initial cone tip diameter of the liquid cone. After the liquid bridge is formed, both the circuit current implying the liquid wetted area on the probe surface and the lifting velocity of the probe are utilized to further regulate the volume of the loaded droplet. Loaded droplets ranging from 60 to 600 pL are obtained via the method with a standard deviation of 4 to 30 pL. Moreover, a dot array is transferred with different loaded droplets. The minimum diameter of the printed dots is about 140 μm with a variation less than 5%. The advantages include the reduced risk of contamination, the droplet-size independent of the size of the probe, and the low cost of the device.
