4.04 Manufacturing of modular electronic devices employing the concept of functionality separations: Towards an adapted workflow for functional printing

Reinhard R. Baumann, Andreas Willert, Thomas Blaudeck

Abstract
In this paper the concept of functionality separation is introduced and applied to conductive layers and two different applications, thin-film batteries and RFID. In both cases manufacturing of products based on printing technologies requires appropriate modifications in the ordinary workflow of graphic arts industry. From the two given examples, the transition from graphical to functional printing motivates an enhancement of the existing workflow by the concept of a functionality layer separation, as additional to the information about the colour ink layers, input for the deposition of functional (i.e. conductive) inks for antennas and chemical components of battery systems is necessary. This can be achieved by introducing new elements using already existing data containers represented as layer information (EPS) or process information (JDF). This information is being separated in the raster image processor (RIP) for the appropriate process step. Furthermore, additional information about post processing steps, e.g. for connecting microelectronics to the printed layers, can be handled.

4.05 Printed electrodes on tailored paper enable extended functionalization of paper

Jouko Peltonen, Anni Määttänen, Roger Bollström, Martti Toivakka, Milena Stępień, Jarkko Saarinen, Petri Ihalainen, Ulriika Mattinen, Johan Bobacka

Abstract
Silver electrodes were flexographically printed on a paper substrate with controlled smoothness, surface energy and barrier properties. The printed electrodes were utilized for further functionalization of the paper substrate. In the first case study, a droplet of water was placed between the printed electrodes and voltage-induced increase of wetting (decrease of contact angle) in the direction parallel to the electrodes was demonstrated. In the second case study, a polyaniline (PANI) layer inkjet-printed on the silver/paper substrate acted as a working electrode  on which  a layer of poly(3,4.ethylenedioxythiophene doped with chloride (PEDOT-Cl) was galvanostatically grown in an electrochemical cell.

Keywords: printed electrodes, functionalization of paper, contact angle

4.06 Printing and coating of T4 phage based bioactive paper

Tarik Jabrane, Meije Laloi, Martin Dubé, Patrice J. Mangin

Abstract
Several bio-agents such as enzymes, viruses or antibodies, can be deposited on paper in order to increase its functionalities. In this work, we demonstrate that a bioactive paper that can destroy E. Coli bacteria can be effectively produced by printing or coating a solution containing T4 phage. We show that the T4 phage resists to the shear stress and infrared drying encountered in printing and coating operation but that a bioactive paper containing only T4 phage on its surface rapidly becomes inefficient though drying. This problem is solved using inks and coating colour containing gelatine. We show that the gel formed at the surface after coating protects the phage from moisture loss for time periods extending to several days.

Keywords: bioactive packaging, printed functionality, pathogen disabling
