Flexible and transparent platform based on oxide transistors for detection and readout of ionizing radiation

Introduction

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.

Market Overview

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. However, 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
• Low cost/complexity

Proposed Solution

By using the patented idea of oxide transistors as direct ionization radiation detectors, coupled with 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.

Action Plan

The action intends to:

1. Identify the most significant market opportunities/applications for the innovative platform.
2. Fabricate/validate a prototype attractive to stakeholders.
3. Develop an IP strategy and a business plan, including a 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 from the Innovation Research and Impact Strategy (IRIS) office at NOVA.
