At the Tallinn Digital Summit, the Graphene Flagship showcased the potential of graphene and related materials to heads of state and government from across Europe with an array of interactive demonstrators and prototypes.
 
In the Graphene Flagship exhibition area, there was an “electronic nose” capable of distinguishing different gases, a graphene-based chromatic eye that uses different graphene photodetectors in an array for broadband optical sensing, and a flexible, graphene based terahertz detector which enables wireless ultrahigh-speed communication.
 
There was also a large area solar cell with high efficiency, retinal implants which can serve as optical prostheses for people who have lost their sight, and a graphene sensor able to detect the electrical activity of the brain.
 
As an example of near market products there was also a motorcycle helmet exploiting graphene in its frame, and a drone with graphene propellers. Graphene Flagship partner Airbus also displayed a model aircraft which illustrates how their current graphene materials research aims to improve their future aircrafts.
 
All of these different demonstrators, prototypes or products were presented to heads of state and governments as they toured the Tallinn Digital Summit and it was a great opportunity for the Graphene Flagship and its members to present the potential of graphene and related materials and the work that is going on within the Graphene Flagship.
 
Visitors to the Graphene Flagship exhibition area included Maris Kucinskis (prime minister of Latvia), Beata Szydlo (Prime minister of Poland), Juha Sipila (prime minister of Finland), Miro Cerar (prime minister of Slovenia), Paolo Gentiloni (prime minister of Italy) and Alexis Tsipras (prime minister of Greece).
 
“The Tallinn Digital Summit allowed us to exhibit some of the many results the Graphene Flagship has achieved during its first four years.” Professor Jari Kinaret, director of the Graphene Flagship, reported.
 
“Tens of start-up and established companies and hundreds of patents are moving graphene and related materials from the lab towards the factory floor,” Professor Andrea C. Ferrari, science and technology officer of the Graphene Flagship and chair of its Management Panel, said. “These have a lot to offer to contribute to the digital innovation of Europe, as was showcased by a selection of demonstrators during this key event for the European Union”.
