Polymer hydrogel microarrays were fabricated by inkjet printing of monomers and initiator, allowing up to 1800 individual polymer features to be printed on a single glass slide.

A printed passive radiofrequency identification (RFID) tag in the ultra-high frequency band for light and temperature monitoring is presented. The whole tag has been manufactured by printing techniques on a flexible substrate. Antenna and interconnects are realized with silver nanoparticles via inkjet printing. A sprayed photodetector performs the light monitoring, whereas temperature measureme...

The technological attraction in organic solar cells is their compatibility to printing processes. However, up to today, nearly no literature on "printed" organic solar cells have been published and the major body of the research work was done by spin coating or blading techniques. Transferring the spin-coating or doctor blading process currently used for the fabrication of bulk heterojunction s...

Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed tracks. The biopolymer–ink interaction results in narrower printed tracks comp...

This paper will describe the process of designing a desktop photo printing system: printer, ink and media. We will compare recent technology trends in photo printers with respect to customer expectations for imaging system performance. We examine the three fundamental component processes of image printing: preparing the image for printing, putting drops on paper, and ink/media interaction. We d...

Direct printing of functional electronic materials may provide a new route to low-cost fabrication of integrated circuits. However, to be useful it must allow continuous manufacturing of all circuit components by successive solution deposition and printing steps in the same environment. We demonstrate direct inkjet printing of complete transistor circuits, including via-hole interconnections ba...

Inkjet printing is considered one of the most promising printing technologies that offers several advantages including high speed, quiet operation and compatibility with a variety of substrates. That makes it an important manufacturing technology serving a wide variety of markets. Though the performance criteria imposed by today’s applications are quite tight already, the future performance req...

Patterning of upconversion luminescent materials has been widely used for anti-counterfeit and security applications, where the preferred method should be easy, fast, multicolor, high-throughput and designable. However, conventional patterning methods are complex and inflexible. Here, we report a digital and flexible inkjet printing based approach for producing high-resolution and high-luminesc...

Inkjet printing technique is proposed for the fabrication of titanium dioxide (TiO2) photoanodes with a synthetic colloidal TiO2 ink. The resultant electrodes were characterised usingmaterials characterisation methods (such as scanning electronmicroscope, X-ray diffraction andUV–vis spectrophotometer) aswell as photoelectrochemical means. The preliminary results indicate that the nanostructure ...
