Inkjet Printing—Process and Its Applications

Abstract

In this Progress Report we provide an update on recent developments in inkjet printing technology and its applications, which include organic thin-film transistors, light-emitting diodes, solar cells, conductive structures, memory devices, sensors, and biological/pharmaceutical tasks. Various classes of materials and device types are in turn examined and an opinion is offered about the nature of the progress that has been achieved.

Slippery Liquid-Infused Porous Surfaces and Droplet Transportation by Surface Acoustic Waves

“…Contact line pinning determines the formation of coffee ring-stains during the drying of droplets containing solute [4], which is an effect way that has to be carefully controlled in droplet microarrays [5] and inkjet printing [6]. It also causes barriers to droplet transport in microfluidics where a large surface area to volume ratio generally exists [7].…”

Inkjet Printing Meets Electrochemical Energy Conversion

“…Inkjet printing has been used for instance to fabricate organic thin film transistors (OTFTs), organic light emitting diodes (OLEDs), solar cells, supercapacitors, sensing devices and biomaterials. [3][4][5][6] Nowadays, it is used in many research laboratories and it is approaching the industrial production level.…”

Electrochemical detection of free chlorine at inkjet printed silver electrodes

“…Stripping voltammetry for chlorine analysis by a system using a silver electrode was mentioned in the patent literature, but no results were shown without clear explanation of the working principle and of the employed apparatus [31]. Recently, inkjet printing of functional devices has attracted a much attention as demonstrated by a growing number of applications, such as the fabrication of disposable, cost-competitive sensors with fast response and low detection limits [32][33][34][35].…”
