The target of i-FLEXIS is the development of an innovative, reliable and low-cost integrated X-ray sensor system
based on heterogeneous inorganic, organic and hybrid components.
It offers real time, direct X-ray detection,
room temperature operation and a "designed for industrial production" approach, delivering operationally robust
and environmentally friendly devices surpassing current state-of-the-art sensors thanks to brand new and
highly needed new functionalities like conformability, flexibility, large active area coupled to low weight, low
power consumption, portability, optical transparency, recyclability and/or sustainable disposability (zero waste,
according to REACH directives).
i-FLEXIS integrates three major novel concepts, recently demonstrated as a
proof-of-principle operation at laboratory scale, allowing for totally new sensing systems: organic single crystals
as the active, X-ray direct sensing material, high mobility thin film transistors based on nm-thin films of novel high
mobility oxide materials operating at ultra-low voltages and flexible transparent electronics, all integrated onto low
cost plastic substrates. These new concepts, will be developed and implemented using micro/nanotechnology
and will be integrated into the final well beyond-the-state-of-the-art sensor system that will consist of multiple
sensing units integrated as a 2D matrix and will be scaled up to 10cm x10cm with printing techniques compatible
with industrial production.
The readout electronics for the whole system will be implemented by a on printed organic and oxide TFTs.
To validate the project outcome, the key-enabling technology of the i-FLEXIS system will be applied to two demonstrative contexts (test vehicles), to highlight its wide application
1) health diagnostic radiation sensor for bone density analyses and to determine the dose on the
2) Identification tags to monitor the airport X-ray screening history of luggage.
