One of the challenges is to design a proper inkjet printhead for demanding trend. Current inkjet printheads are mostly based on either piezoelectricity or heat. This paper presents an inkjet printhead using a magnetostrictive principle. [...]
We report gravimetric measurements of droplets, traceable to the SI, that enable the correction and calibration of optical measurements routinely used to monitor and control the dispensing of droplets from inkjet printers. This innovation results [...]
This study investigates the effect of droplet deposition dynamics on inkjet-printed line features of deionized water using numerical analysis. Simulation results show that kinetic energy dissipation during the droplet deposition process transforms into inner wave [...]
The application of mechanical stress – e.g. generated by ultrasonic cavitation - breaks the particle agglomerates apart. Also, liquid is pressed between the particles. Different technologies are commonly used for the dispersing of powders into [...]

Inkjet printing has a high potential for cost reduction in solar cell and thermoelectric industry. This study demonstrates that silicon thin films can be produced by inkjet-printing of a silicon ink followed by consequent drying [...]
All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used [...]

Aqueous silver nitrate ink (5 moles/liter) mixed with poly(N-vinyl-2-pyrrolidone) (PVP) was employed in a piezoelectric inkjet printing apparatus to construct conductive patterns on ultraviolet/O3-treated polyimide substrates. At a pulse amplitude of ±38 V, single droplets [...]
Advances in micro- and nano-scale processing technologies have provided various therapeutic opportunities in the field of medicine. While techniques developed for tissue engineering and regenerative medicine applications have had initial successes in building a number [...]

Printed electronics has become a promising technology due to its lithography and vacuum-free processing. However, several issues remain unsolved: most printable semiconductors nowadays are organic molecules with low mobilities and poor air and moisture stability. [...]
Solar cell modules generally are bonded with photovoltaic ribbon using silver paste to increase photovoltaic conversion efficiency. However, the joint strength of silver paste between the aluminum back electrode and the ribbon may be the [...]
This paper addresses the EHD printing of a high aspect ratio of metal lines as a means of forming a high conductivity of metal lines. As stated earlier, EHD printing is advantageous over conventional inkjet [...]
