“…The performance of UWB antennas fabricated using the proposed process was found to be equivalent to that of similar antennas fabricated using conventional lithographic processes. These results are promising for low-cost, high-volume manufacturing of RFID tags, as both inkjet printing and electroless plating are amenable for roll-to-roll processing [26]. The simplicity of using an office inkjet printer for defining conductive patterns should enable the advent of flexible, low-cost devices for applications in diverse areas, such as biomedical diagnostics, flexible electronics, ubiquitous sensing platforms etc.…”

A low-cost fabrication process for forming conductive copper lines on paper is presented. An office inkjet printer was used to deposit desired patterns of silver nitrate and tannic acid solutions sequentially on paper. Silver nitrate was instantaneously reduced in situ on paper by tannic acid at room temperature to form silver nanoparticles, which acted as catalysts for the subsequent electroless deposition of copper. The copper films were 1.8 μm thick, and the sheet resistance of the copper film on paper was 9 Ω/ . A dual monopole ultrawide band antenna was fabricated on paper and its performance was equivalent to that of a similar antenna fabricated on a copper-film covered Kapton substrate using conventional lithographic processes. The paper-based conductive copper films fabricated using the facile process presented herein will aid the development of low-cost flexible circuits and sensors.

“…3, there is a dramatic reduction in both the perceived contrast and colorgamut volume of the LCD when viewed outdoors, where as the print color gamut does not change significantly between these two light environments. 41 Full sunlight can be in excess of 30,000 lux, and the disparity between paper, e-Paper, and conventional LCD performance can be dramatic in outdoor lighting. Some transmissive/emissive display manufacturers attempt to use "% of NTSC" as a standard to evaluate e-Paper displays.…”

“…History, maturity: A new approach to electrophoretic displays, coined electrokinetic technology by Koch and co-workers at Hewlett-Packard, was first reported at SID 2009. 41 Since this time, HP had demonstrated fully functional and flexible segmented e-skin modules that were fabricated using roll-to-roll manufacturing. Yeo and co-workers at HP have more recently demonstrated in 2010 both gray scale and pixelation with an active-matrix backplane.…”

Abstract— The commercial success of monochrome electronic paper (e‐Paper) is now propelling the development of next‐generation flexible, video, and color e‐Paper products. Unlike the early battles in the 1980s and 1990s between transmissive and emissive display technologies, there is a extraordinary diversity of technologies vying to become the next generation of e‐Paper. A critical review of all major e‐Paper technologies, including a technical breakdown of the performance limitations based on device physics and commentary on possible future breakthroughs, is presented. In addition, the visual requirements for color e‐Paper are provided and compared to standards used in conventional print. It is concluded that researchers have much work remaining in order to bridge the significant gap between reflective electronic displays and print‐on‐paper.

“…A set of roll-to-roll (R2R) processing capabilities for making fine-scale circuitry and physical features on plastic substrates that are compatible with the needs of reflective displays was also developed [8]. The processes are scalable to large web widths, and the fine features enable highdensity circuits and future integration with more complex passive and active elements.…”

A novel architecture and proprietary electronic inks were developed to provide disruptive digital-media solutions based on an electrokinetic technology platform. The flexible reflective electronic media (eMedia) was fabricated by imprinting three-dimensional microscale structures with a roll-to-roll manufacturing platform. The HP technologies enable the required attributes for eMedia, such as low power, transparency, print-quality color, continuous levels of gray, and lowcost scalability. Pixelation was also demonstrated by integrating with the prototype oxide thin-film transistor backplane, and the system architecture was further developed by stacking primary-colorant layers for color reflective-display application. The innovations described in this paper are currently being developed further for the eSkins, eSignage, and ePaper applications.
