Periodic Reporting for period 1 - INNPAPER (Innovative and Smart Printed Electronics based on Multifunctionalized Paper: from Smart Labelling to Point of Care Bioplatforms)

Teaser

Summary

The rising production and use of short lifetime electronic devices nowadays results in the generation of an increasing volume of electronic waste, which is becoming a growing environmental and health The rising production and use of short lifetime electronic devices nowadays results in the generation of an increasing volume of electronic waste, which is becoming a growing environmental and health problem due to their hazardous substances content. To tackle the fast increasing waste stream, treatment, recycling and/or re-use of electronics at the end of their life is essential. In this context, the use of paper as functional part of electronic components is emerging as a promising solution. In spite of the large potential of paper as the core-component of electronic devices, existing paper-based electronic systems are still scarce.
INNPAPER project aims at providing a plastic free electronic platform integrating three paper-based devices (battery, display and NFC system) printed on a multifunctional paper sheet. The platform is designed to enable the subsequent production of multiple use-cases by incorporation of specific components and sensors. The feasibility and versatility of the platform will be demonstrated in the project through the generation of 3 use-cases:
â€¢ Smart-labels for food packaging
â€¢ PoC quantitative immunoassays for drug (THC) and caffeine detection
â€¢ PoC genetic assays for rapid diagnosis of infectious diseases

Work performed

During the first period (M1-M12), the main results achieved are the following:
WP1. Project coordination and management. A private area with restricted access for the project partners was created. In addition to the project kick-off meeting held at CIDETEC, two consortium meetings have been held at the Aalto University and VTT facilities in Finland (M6) and in Brussels (M12). A risk management plan compiling the different issues that might hinder the achievement of the project objectives has been elaborated.
WP2. Development of tailor-made (multi)functional (nano)paper. The first activity performed within this WP was the definition of the paper/nanopaper requirements based on the specifications of the electronic platform and derived use-cases. The base paper materials were selected within the PowercoatÂ® range from GUARRO CASAS and the nanopapers range from Aalto University and VTT. Following different strategies, the following properties have been achieved so far: Electrical conductivity, superhydrophobicity, barrier properties to oxygen and moisture and bulk resistance to water and organic solvents. Moreover, fluidic channels on nanopapers with anti-fouling and protein detection properties for the lateral-flow immunoassays (use-case 2) have been also developed. For the genosensors (use-case 3), two methods to obtain the grinding surface on paper in the DNA release chamber have been assessed.
WP3. Development of devices aiming at the configurable common platform. During the first year, the activities of this WP have been focused on the definition of the devices specifications, the development of the key materials and the design of the configurations of the individual devices. In particular, cellulose-based inks for batteries and electrochromic displays have been developed and their suitability for the screen-printing technique has been demonstrated. The design and components for the NFC system have been selected.
Transfer of printed electronics from plastic to paper substrates has been also successfully addressed in this period for some of the systems such as environmental sensors for the smart labels (use-case 1). Regarding the development of the immunosensors (use-case 2), an initial design of four electrodes on a fluidic channel has been printed on paper and the detection strategy and bioreagents for each application have been selected and tested. For the genosensors (use-case 3), the two methods to realize the surface of grinding chamber have been validated. A first scheme of the microfluidic channels and chambers has been designed and validated through the realization of some prototypes. Tests of DNA amplification (LAMP) after bacteria grinding on paper have been performed, being positive and repeatable.
WP4. Integration and manufacturing of the common electronic platform and use-cases. The designs (including dimensions of the platforms and size and location of the different components) have been proposed for the 3 use-cases. The process flows to manufacture the 3 demonstrators have been also proposed.
WP5. Validation and manufacturing transfer assessment. This WP has not started yet.
WP6. Eco-design, LCA, re-use and recycling. The scope, system boundaries and methodology for the Life Cycle Assessment have been defined. A preliminary investigation of the potential environmental impacts of the paper-based printed electronic devices has been carried out. The INNPAPER products are still under development and at this stage of the study the investigation was performed on a literature review basis.
WP7. Communication, dissemination and exploitation. The project visual identity, website, communication material and market studies have been generated and first versions of the DMP and the PDER have been elaborated. Using node analysis techniques of the communities following INNPAPER on social media, a relevant stakeholder database has been generated. In 2018, INNPAPER had 6 media appearances, the projectâ€™s partners have enga

Final results

INNPAPER will develop and demonstrate a new disruptive and sustainable, configurable paper-based platform for electronics. One of the main advances will be total replacement of plastic by paper. To enable this, WP2 will gather together the individual tailored properties in the same paper sheet to generate a very innovative multifunctional paper meeting the needs of electronics devices and applications planned in INNPAPER. Moreover, in INNPAPER the cellulose will be not only an inert substrate, but used as an electronic material and active component. Thus, in INNPAPER the paper will act as current collector and intrinsic electrode (conducting / semiconducting paper), as matrix to host the electrochromic species and the electrolyte in electrochromic displays (ECDs), as additive to tailor the viscosity of the inks, as insulator in batteries, etc.
The configurable platform will be the basis for the manufacture of the INNPAPER use cases.
By showcasing its multi-functionality, the INNPAPER solutions will enhance the attractiveness of paper as a substitute to the materials commonly used in printed electronics, such as polyimide and epoxy-based materials, as well as other plastic foils (PET, PEN), thus reducing the environmental impact of electronics.
Furthermore, by connecting the European forest fibre industry and the printed electronics community together around open pilot lines already available at RTOs, INNPAPER will have a major impact in providing the industry with new market opportunities based on paper-based electronics for a broad range of application areas.
Finally, since the common platform and the use cases will include different electronic devices, INNPAPER will demonstrate the use of paper/cellulose as a solution to provide sustainable electronic systems in a wide range of applications.
