Simultaneous formation of fine and large-area electrode patterns using screen-offset printing and its application to the patterning on adhesive materials

Abstract

Additive-type printing techniques such as gravure-offset printing and screen printing are effective for low-cost and ecofriendly electrode pattern formation. Gravure-offset printing is effective for fine pattern formation with widths on the order of 10–20 µm, whereas screen printing is effective for the formation of large-area patterns. However, it is difficult to simultaneously form fine and large-area patterns using these printing techniques. In this study, we demonstrate that fine (minimum width of 15 µm) and medium- as well as large-area patterns can be formed simultaneously using our developed screen-offset printing technique, which is a combination of screen printing on a silicone blanket and transfer printing from the blanket to a substrate. Furthermore, we demonstrate the application of our method to printing on adhesive materials, which allows electrode formation without applying heat to the film substrate.

Fabrication of a Textile-Based Wearable Blood Leakage Sensor Using Screen-Offset Printing

“…To address these issues, we combine two technologies. The first is a simple formation of conductive patterns on textiles by applying a screen-offset printing technique that we developed [ 8 , 9 , 10 , 11 ]. Printing is very useful technique, since it enables rapid pattern formation at low cost.…”

High-Resolution Graphene Films for Electrochemical Sensing via Inkjet Maskless Lithography

“…Solution-phase printing of nanomaterial-based conductive inks has helped facilitate the scalable manufacturing of flexible electronics − in a low-cost, high-throughput fashion. − These printing protocols have expedited the advent of new technologies for diverse applications including those associated with energy storage, flexible electronic displays, smart packaging, and diagnostic sensors . Graphene-based inks have shown great promise in enabling these applications due to inherently advantageous material properties ( e.g.…”

Adhesive-bandage-type Blood-leakage Sensor Fabricated by Screen-offset Printing

“…To overcome these problems, we applied a screen-offset printing method (7)(8)(9)(10)(11)(12)(13) that we previously developed to fabricate patterns on an adhesive material. Figure 1 shows a schematic image of the screen-offset printing method.…”

“…As a result, the conductive ink can be transcribed onto the adhesive to form the electrode patterns for the sensor. (11) In the present experiment, we first screen- printed an interdigitated pattern using Ag ink (SSP2801, Toyobo) on the blanket using a screenprinting machine (Cube1515, Mino Group). Then, we thermally annealed the ink on the blanket at 150 ℃ for 30 min.…”
