Direct fabrication of microelectrodes on a polymer substrate using selective ultrashort pulsed laser ablation of inkjet-printed Ag lines" (2012). An inkjet-based ultrashort pulsed laser patterning on a polymer substrate is presented with high-laser scanning speeds. The effects of the laser processing parameters on the ablation characteristics were studied to accomplish damage-free laser ablatio...

Smaller form factors and dynamic applications have made flexible circuits an essential part of today’s electronic devices. Although flexible electronics is well established and constantly growing industry, this technology has its limitations. Flexible circuits can typically bend along one axis and cannot therefore conform to arbitrary shapes like for example human skin. The transition to stretc...

Inkjet printing of functional materials has drawn tremendous interest as an alternative to the conventional photolithography-based microelectronics fabrication process development. We introduce direct selective nanowire array growth by inkjet printing of Zn acetate precursor ink patterning and subsequent hydrothermal ZnO local growth without nozzle clogging problem which frequently happens in n...

A series of inkjet printing processes have been studied using graphene-based inks. Under optimized conditions, using water-soluble single-layered graphene oxide (GO) and few-layered graphene oxide (FGO), various high image quality patterns could be printed on diverse flexible substrates, including paper, poly(ethylene terephthalate) (PET) and polyimide (PI), with a simple and low-cost inkjet pr...

Inkjet printing is a very powerful digital and mask-less microfabrication technique that has attracted the attention of several research groups working on electrochemical energy conversion concepts. In this short review, an overview is given about recent efforts to employ inkjet printing for the search of new electrocatalyst materials and for the preparation of catalyst layers for polymer elect...

During the last couple of years several ink manufacturers have presented metal nano-particle inks for inkjet printing. These inks provide low resistances on plastic and paper substrates, thus enabling manufacturing of high-conductivity conductors that could be used in circuit boards. Inkjet printing of a commercial silver nano-particle ink on paper and plastic substrates has been investigated. ...

wileyonlinelibrary.com properties that make it diffi cult for additive, high throughput, scalable fabrication processes. For example, in the context of inkjet printing, the combination of viscosity, surface tension, and density alone suggest Ga–In alloy to be a non-printable fl uid without modifying either the material or the atmosphere (Supporting Information). Additionally, the fast-forming o...

Inkjet printing techniques for the etching of polymers and their application to the fabrication of organic electronic devices are reviewed. A mechanism is proposed for the formation of via holes in polymer layers through inkjet printing with solvent, and recent achievements in the fabrication with inkjet etching of various three-dimensional microstructures (i.e., microwells, microgrooves, hexag...

As the needs for low-cost rapidly-produced microfluidics are growing with the trend of Lab-on-a-Chip and distributed healthcare, the fully inkjet-printing of microfluidics can be a solution to it with numerous potential electrical and sensing applications. Inkjet-printing is an additive manufacturing technique featuring no material waste and a low equipment cost. Moreover, similar to other addi...

Complex cellular patterns and structures were created by automated and direct inkjet printing of primary embryonic hippocampal and cortical neurons. Immunostaining analysis and whole-cell patch-clamp recordings showed that embryonic hippocampal and cortical neurons maintained basic cellular properties and functions, including normal, healthy neuronal phenotypes and electrophysiological characte...
