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.

Background: Flexible polydimethylsiloxane (PDMS) with linear microstructures plays an indispensable role in the fields of bioengineering and flexible sensing due to their excellent light transmittance and biocompatibility.Aim: We aim to address the challenge of achieving simple, environmentally friendly manufacturing of PDMS linear microstructures.Approach: A direct molding technique for fabricating high-quality PDMS microstructures by electrohydrodynamic printing with a cone jet was proposed. In this method, the viscosity of PDMS was changed by still setting at room temperature to print high-quality PDMS linear microstructures, without introducing any other chemical reagents. Results:The influences of the still-setting time and curing temperature on the surface topography and jet morphology were studied, and the impacts of working parameters on the width of linear microstructures and jet stability were also investigated. By optimizing the still-setting time and printing parameters, the PDMS linear microstructures with a line width of 165.6 μm were printed. Conclusions:This method provides a simple and environmentally friendly process to fabricate PDMS linear microstructures and facilitate their application.

Current methods for thin film sensors preparation include screen printing, inkjet printing, and MEMS (microelectromechanical systems) techniques. However, their limitations in achieving sub-10 μm line widths hinder high-density sensors array fabrication. Electrohydrodynamic (EHD) printing is a promising alternative due to its ability to print multiple materials and multilayer structures with patterned films less than 10 μm width. In this paper, we innovatively proposed a method using only EHD printing to prepare ultra-micro thin film temperature sensors array. The sensitive layer of the four sensors was compactly integrated within an area measuring 450 μm × 450 μm, featuring a line width of less than 10 μm, and a film thickness ranging from 150 nm to 230 nm. The conductive network of silver nanoparticles exhibited a porosity of 0.86%. After a 17 h temperature-resistance test, significant differences in the performance of the four sensors were observed. Sensor 3 showcased relatively superior performance, boasting a fitted linearity of 0.99994 and a TCR of 937.8 ppm/°C within the temperature range of 20 °C to 120 °C. Moreover, after the 17 h test, a resistance change rate of 0.17% was recorded at 20 °C.
