In the 10-year perspective, the vision for flexible electronics and optoelectronics is built upon five key technology enablers (TE), which are then unified around two streams of applications and summarized in Fig. 52. Key TEs are T1 Fabrication and integration, T2 Energy, T3 Connectivity, T4 Sensing, and T5 TCO. The two streams of applications identified by industry are D1 Smart Portable Devices and D2 Energy Autonomous Sensors.

The graphene flagship consortium will aim in the first 30-month period towards the development and the increase in maturity of the TEs listed above. The first period will be succeeded by the realization of demonstrators. For instance different fabrication approaches will be developed such as printing of graphene inks, but also the scaling up the manufacturing of integrated components will be investigated. The consortium will address also the need for developing flexible versions of essential energy related technologies, but the flexibility creates also new requirements and opportunities for dedicated connectivity solutions such as radio communication. Biocompatible large area sensors and flexible version of these will also be one of the key technology enablers developed in this area. Finally, electromechanical and reliability tests of individual layers, substrates, devices and full systems will be performed.

In the first D1 (“Smart Portable Devices”) application stream we expect the following major prototype demonstrators to be realised:

Year 2: Wearable Smart Device for Sensing and Connectivity – Leveraging both existing and new, graphene based technologies this demonstrators will show the potential for cost advantage and/or performance enhancement in wearable, connected devices for the emerging market fitness and wellness application.

Year 3: Bendable and Portable Smart Device for Entertainment and Browsing Applications – Combining advanced material, energy, connectivity and integration/manufacturing technologies developed within the Flagship projects with display and logic processors from external suppliers, this demonstrators will showcase radically new solutions for game control and user interaction and manipulation of content.

Year 4 and Beyond: Partly or Fully Flexible Mobile Phone – The most advanced
and challenging demonstrator that can be envisaged at this stage will attempt to reproduce important functionalities of a smart phone in a partly or fully flexible format.

In the D2 (“Energy Autonomous Sensors”) stream we expect the following major prototype demonstrators to be realised:

Year 2: G-based chemical and bio sensors – Exploiting both existing and new sensing devices with high or ultra-high sensitivity and chemical stability, based on graphene functionalization chemistry, intrinsic biocompatibility and ambipolar
characteristics of G-FET devices.

Year 3: Energy Harvesting and Storage devices – Developing energy related technologies tailored for flexible substrates such as flexible batteries, super-capacitors and their integration with harvesting devices. This milestone aims to provide the “engine” to propel the autonomous sensor devices.

Year 4 and beyond: Integrated Smart Sensor Units with RF connectivity – At first, we will combine RF device and circuit applications based on ambipolar non-linear graphene electronics for RF connectivity with Analog Sensor Interfaces, and integrating both on a flexible foil substrate. Finally, we will develop and provide the necessary infrastructure towards “graphene-augmented” smart integrated sensors on flexible substrates, with the necessary energy harvesting and storage capability to work autonomously and wireless connected to the environment.
