Inkjet printing allows localized, contact-free deposition of liquids onto arbitrary substrates. In this article we demonstrate the fast formation of high-quality self-assembled monolayers (SAMs) on gold surfaces. Using a selective etch process, we verify the uniformity of the deposited spots. A direct comparison with microcontact-printed SAMs on Au revealed similar resist quality as inkjet-depo...

Beyond printing text on paper, inkjet printing methods have recently been applied to print passive electrical and optical microparts, such as conductors, resistors, solder bumps and polymeric micro lenses. They are also useful to print micro-electro-mechanical systems (MEMS) as sub-millimeter sensor and actuator arrays, such as multifunctional skins applicable to robotic application and ambient...

Inkjet printers are non-impact printers which print text and images by spraying tiny droplets of liquid ink onto paper. Besides the well known small inkjet printers for home and office, there is a market for professional inkjet printers. Inkjet printers are used to form conductive traces for cir cuits, and color filters in LCD and plasma displays. That makes the printing quality is an important...

Inkjet printing is an attractive deposition tool to complement the traditional processing methods used in microelectronics integration. Its maskless, digital and non-contact nature provides many generic benefits, such as savings in processing steps and material usage, production flexibility and scalability to large areas. In addition, inkjet printing can be utilized in the integration of e.g. s...

In this study, the modulation transfer functions of prints, which included both mechanical and optical dot gain effects were measured from samples printed by an ink jet printer on glossy-coated, matt-coated and uncoated papers. The MTF of prints were measured from sinusoidal patterns and Fourier transforms of line spread functions from one-pixel line and step images. The MTF of print from three...

To support color and high printing quality of a printer, we developed a piezoelectric type inkjet print head. In this system we adopted piezoelectric share mode, which is superb in ink drop control and can be applied to many fields.

Over the past century, synthetic adhesives have largely displaced their natural counterparts in medical applications. However, rising concerns over the environmental and toxicological effects of the solvents, monomers, and additives used in synthetic adhesives have recently led the scientific community to seek natural substitutes. Marine mussel adhesive protein is a formaldehyde-free natural ad...

Stable ink containing highly dispersed graphene nanosheets (GNSs) for inkjet printing on polyimide (PI) film has been successfully prepared by the adsorption of sodium n-dodecyl sulphate (SDS) and adjusting the pH value to 10 by ammonia. Conductive features on a flexible PI film were fabricated by inkjet printing the stable ink directly on a substrate. With higher number of printing cycles, the...

Liquid-based inkjet printing is considered as a constructive (rather than destructuve) low-cost technique for printed circuit board fabrication. A convenient way of depositing silver films and lines using inkjet technology is to generate silver nanoparticles (AgNP) that can be dispersed and stabilized in solutions, processed into desired patterns and subsequently annealed. To avoid the aggregat...

This paper presents an inkjet printing capacitive microwave sensor for toxic vapor detection. The designed sensors were presented and fabricated with success. The experiments show sensitivity to ethanol vapor according to the S parameters. It is equal to 0.9 kHz/ppm and 1.3 kHz/ppm for the sensors based on 5 and 50 sensitive layers respectively. This sensor will be integrated into real-time mul...
