We report on inkjet printing of aqueous colloidal suspensions containing monodisperse silica and/or polystyrene nanosphere particles and a systematic study of the morphology of the deposits as a function of different parameters during inkjet printing and solvent evaporation. The colloidal suspensions act as a model ink for an understanding of layer formation processes and resulting morphologies...

A rapid advanced packaging concept, consisting of inkjet photopolymer printing and Ag nanoparticles printing, was investigated for the construction of a pressure sensor package. Acrylatetype 3D package housing with 7 through-holes was printed with a polyjet printer and the throughvias and connection pads were manufactured via Ag glue dispensing and inkjet printing of Ag nanoparticle ink. The fl...

Recently, there has been considerable interest in adapting printing approaches that are typically used in the graphic arts to the printing of electronic circuits and circuit components. We report the fabrication of solution-processed oxide transistors using inkjet printing. A zinc tin oxide sol-gel precursor is utilized as the ink for directly printing a thin uniform semiconducting layer. The p...

Banding can be a major defect in inkjet printing. Knowing the visual sensitivity threshold of inkjet banding is therefore useful for understanding and pushing the technological limit of inkjet printing. There are many reports on the measurement of the human contrast sensitivity using self-luminous sinusoidal contrast targets. There are also reports on measuring the contrast sensitivity of sinus...

Recently, inkjet-printing has gained increased popularity in applications such as flexible electronics and disposable sensors, as well as in wearable sensors because of its multifarious advantages. This work presents a novel, low-cost immobilization technique using inkjet-printing for the development of an aptamer-based biosensor for the detection of lysozyme, an important biomarker in various ...

We report a direct write inkjet printing technique for fabricating a flexible antenna on textile for use in smart textile applications such as wearable systems (Rienzo et al. 2006). The complete antenna was deposited entirely using inkjet printing. The inkjet printed antenna is based on a half wavelength dipole antenna offering a planar structure and acceptable size. The printable silver nanopa...

A ‘button-shaped’ three-dimensional (3D) radio-frequency identification (RFID) tag combining 3D printing and inkjet printing technologies in fabrication for the first time is proposed. The button shape facilitates the tag’s integration with clothes for the purposes of identification and access control. The proposed tag features a compact size (radius 15 mm, height 7.5 mm) and a good performance...

Organ printing offers a great potential for the fabrication of three-dimensional (3D) living organs by precisely layer-by-layer placing various tissue spheroids. Such fabricated organs may replace some damaged or injured human organs, emerging as a promising solution to the problem of organ donor shortage. As one of the key enabling technologies for organ printing, inkjetting has been received ...

The present work demonstrates a valuable approach to developing quartz crystal microbalance (QCM) sensor units inexpensively for reliable determination of analytes. This QCM sensor unit is constructed by inkjet printing equipment utilizing background noise removal techniques. Inkjet printing equipment was chosen as an alternative to an injection pump in conventional flow-mode systems to facilit...

This work introduces and demonstrates the concept of Lab-on-a-Printer whereby microfluidic components are integrated with inkjet dispensers. This concept allows for multi-functional microfluidic materials processing to be performed on chip and direct post-process printing of those materials enabling printing of programmable gradients and more generally structures with programmable composition. ...
