Tapani RyhänenNokia, Finland
Tapani Ryhänen is heading Nokia Technologies Business Unit’s Sensor Systems Business Line that operates in Cambridge and Espoo and focuses on high added-value solutions for customers’ measurement problems, based on innovative sensors, ultra-low power signal and information processing, algorithms, and wireless connectivity. Before his current role he was leading Nokia’s research in sensor and material technologies, especially focusing on various applications of nanotechnologies. During his career in Nokia he has been responsible for Nokia’s strategic research in the areas of future user interfaces, future device architectures and interfaces, mechanics and miniaturization. He is one of the forerunners of implementing sensors in mobile devices, and he is one of the originators of projects that led to BT LE and MIPI Unipro standards. His previous work at Nokia also covers wellness and health applications, ambient intelligence, RF MEMS, microsystems, architectures and interfaces of sensor modules and mass storage solutions. He has authored over hundred publications and over fifty granted patents on superconducting thin-film devices, micromechanical sensors and actuators, biomagnetic measurements, nanotechnologies, and mobile phone technologies and applications. His is one of the creators of the Nokia Morph concept and an author and editor of a book “Nanotechnologies for Future Mobile Devices”. He is a member in the Scientific Advisory Committee of the EU Graphene Flagship Project, advices the X PRIZE Foundation on its Nokia Sensing X Challenge for revolutioning digital healthcare, and is a board member of the Nokia Foundation.

Abstract
The combination of outstanding chemical, electrical, optical, mechanical and thermal properties of graphene makes it an interesting new material for a multitude of applications in flexible electronics. The key trends and drivers in flexible electronics are discussed, and the applications for graphene and 2D materials summarised. A short description of the flexible electronics work in the EU Graphene Flagship is given. Nokia’s work in applying 2D materials to flexible electronics is described by examples in sensor and battery technologies. Finally, the commercial and technical challenges in productising graphene technologies are discussed.
