High-performance, Flexible, AUTOnomous Systems manufactured with Unique, Industrial ROLL-to-roll equipments (ROLL-OUT) is a project funded by the European Union within the H2020 program. It is a 36 months project involving 10 partner organizations – 5 research organizations and 5 industrial partners, from 6 different European member countries.

The ROLL-OUT project combines the competences of top-level European research groups and large and small- and medium-size industries involved in Large Area Electronics. ROLL-OUT intends to create a multi-purpose technology for thin, large-area, high-performance, smart, and autonomous systems comprising integrated circuits (ICs), sensors, and electronics, advancing the packaging, automotive interiors and textile industries beyond their traditional scope. The key features are high-performance circuits and components. Novel, hybrid, moderate-temperature, roll-to-roll processes, namely Sputtering, Atomic Layer Deposition (ALD) and Screen-printing on thin, flexible, large-area substrates are methods to be used.

The ICs are based on array of thin-film transistors (TFTs) fabricated using metal-oxide dielectrics and semiconductors. It is well-known that it is essential to utilize high performance device fabrication processes, namely Sputtering and ALD, to create the best-performing transistors and circuits on flexible substrates using metal-oxide materials. –Unique R2R Sputtering (developed by POLYTEKNIK) and R2R ALD (developed by PICOSUN) will be utilized to create the best performance transistors and ICs. Critical materials, namely Indium, will not be used in the project to create a sustainable solution for the flexible electronics industry. A novel hybrid-integration technology will be also utilized in ROLL-OUT.

Large-area sensors used in ROLL-OUT will predominantly be pressure sensors (developed by CIDETEC) and temperature sensors (developed by IISB).

Thin, high charge-density batteries will be developed and used in the autonomous systems in ROLL-OUT. University of Uppsala (UU) will develop a thiophene-based terephtalic acid derivative battery with capacities of 216 mAh/g. A cell voltage of 2 V will be obtained from the batteries.

The end-users of the developed technology within ROLL-OUT will be MAIER, LOGOPLASTE and FOV for application in automotive, consumer packaging and textile industries, respectively.
