Description du projet
Un détecteur de rayonnements ionisants de nouvelle génération fondé sur des transistors à oxyde brevetés
Les rayonnements ionisants, des rayonnements de haute énergie qui peuvent arracher les électrons des atomes ou des molécules par ionisation, peuvent endommager les cellules et leur ADN. La surveillance de la dose de radiations ionisantes revêt une importance critique dans un certain nombre d’applications allant du secteur de l’énergie à la sécurité civile, en passant par les soins de santé. Les détecteurs de rayons X flexibles et portables constituent une nouvelle solution potentielle dans les technologies de nouvelle génération, mais aucune innovation ne combine actuellement portabilité, haute résolution, faible coût, complexité et autres caractéristiques souhaitées. Le projet FLETRAD, financé par l’UE, développera une plateforme flexible et transparente et répondant à tous les défis actuels, en exploitant des transistors à oxyde brevetés comme détecteurs directs de radiations ionisantes.
Objectif
Ionizing radiation presents a known health risk, but if used controllably it can be the basis of relevant applications spanning from healthcare to civil security. Either for proper control of the dose received by patients in medical treatments or workers in radiation hazardous environments, or for high resolution imagers, proper quantification of the radiation doses is demanded. The x-ray detectors market represented 2.5 Bn$ in 2020, and flexible/wearable X-ray detectors are seen as breakthrough innovations for next-gen devices. But to date, there is not a detection technology offering a combination of conformability, portability, large active area, small interference with the radiation received, potential for high resolution and low cost/complexity. By using the patented idea of oxide transistors as direct ionization radiation detectors coupled to the knowledge derived from ERC Starting Grant TREND in miniaturized oxide electronics using sustainable materials and processes, FLETRAD proposes a platform tackling all those requirements and going beyond them. It creates the breakthrough market opportunity of having a fully flexible and transparent radiation sensing platform, using seamlessly integrated oxide transistors both for sensors and electronics.
The action intends to identify the most significant market opportunities/applications for the innovative platform, fabricate/validate a prototype attractive to stakeholders, develop an IP strategy and a business plan, including the detailed analysis of the identified business opportunities. The work will be done at CENIMAT|I3N (NOVA), in a group pioneering oxide electronics, with full support of the Innovation Research and Impact Strategy (IRIS) office at NOVA.
FLETRAD has the support of key-players in ionizing radiation/flexible electronics, contributing to take our ideas into impactful market and societal needs.
