A novel Planetary Motion of Ferrofluid Drops in a Rotating Magnetic Field

Chen C-Y, National Chiao Tung University, TW

Driven by an external rotating field, a novel phenomenon of planetary-like double rotations, such as a local self-spin of individual drops and the global revolution of the drop array, is uncovered in arrayed ferrofluid drops. [...]

Introducing a Digital Micropump for Driving a Droplet in a Microfluidic Channel

Rezaei Nejad H., University of British Columbia, CA

This paper presents a novel pumping technique which is compatible with both digital and continuous microfluidic platforms. In essence, a target droplet (referred to as the pumped droplet) is pumped by actuating the secondary droplet [...]

Repeated Duplication in EHD Line Patterning on a Non-Conductive Substrate Based on Controlling the Polarity of Applied Voltages

Son S., Lee S., Choi J., Sungkyunkwan University, KR

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 [...]

A Study of Molten Lead-Free Solder Deposited by Inkjet Printing for Interconnections of Thin-Film Solar Cell Modules

Chen W-M, Wang C-H, Hwang W-S, National Cheng Kung University, TW

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 [...]

Ink-jet Printed CdS Thin Film Transistors Fabricated In-situ by Micro-reaction

Ramos J.C., Kabir D., Mejia J.I., Martinez C.A., Quevedo-Lopez M.A., University of Texas at Dallas, US

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. [...]

Bio-ink for inkjet printing of living cells

Ferris C.J., Gilmore K.J., Beirne S., McCallum D., Wallace G.G., in het Panhuis M., ARC Centre of Excellence for Electromaterials Science (ACES), AU

This abstract summarises our recent work on the development of a bio-ink tailored for the controlled deposition of cells by inkjet printing. Direct printing of living cells is an emerging approach to the fabrication of [...]

Bioprinting Technology for Regenerative Medicine Applications

Yoo J., Wake Forest Institute for Regenerative Medicine, US

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 [...]

Effects of Inkjet Printing Parameters on Conductive Line Patterns for Flexible Electronics Applications

Tsai H.L., Hwang W-S, Liu Y-F, Wu J.-T., Hsu S.L.-C., National Cheng Kung University, TW

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 [...]

Effects of Poly-(N-vinyl-2-pyrrolidone) Additive on Direct-Inkjet-Printed Silver Nitrate Conductive Lines

Liu Y-F, Feng P.H., Tsai H.L., Hwang W-S, National Cheng Kung University, TW

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 [...]
