X-ray technology has taken a significant leap forward. The Industrial Technology Research Institute (ITRI) and InnoCare Optoelectronics Corp. have collaborated to introduce an innovative perovskite X-ray sensing technology. This breakthrough offers superior X-ray conversion efficiency and high-resolution imaging while enabling rapid imaging at lower radiation doses, enhancing both detection performance and user experience.
The development of this technology stems from a serendipitous discovery made three years ago during ITRI’s research on perovskite solar cells. Researchers found that perovskite materials exhibit exceptional X-ray absorption capabilities, producing high-contrast images even under low-dose X-ray exposure, revealing immense potential for medical and industrial applications.
However, integrating perovskite into X-ray sensing technology has posed challenges in material stability, process uniformity, and mass production scalability. Traditional X-ray sensors primarily use cesium iodide (CsI) or gadolinium oxysulfide (Gd₂O₂S, GOS), but these technologies still face limitations in resolution and production costs. While perovskite offers distinct advantages, achieving uniform large-area coating and long-term stability has been a key technical hurdle.
Fu-Ming Lin, Section Chief at ITRI’s Green Energy and Environmental Research Division, stated that after three years of technological breakthroughs, ITRI successfully optimized perovskite formulations and spray-coating techniques, significantly improving material uniformity and durability, ensuring stable long-term operation.
This technology demonstrates high X-ray absorption, low power consumption, and cost-effective manufacturing, laying a foundation for next-generation X-ray sensing solutions.
In medical applications, perovskite X-ray sensors can generate high-resolution images with significantly lower radiation doses, reducing radiation exposure for patients while minimizing image artifacts, thereby enhancing diagnostic accuracy. Its flexible design allows for greater adaptability and patient comfort, overcoming the limitations of traditional rigid sensors, making it ideal for dental, orthopedic, and mammography imaging.
Beyond healthcare, this technology holds significant potential in industrial and semiconductor inspection.
For instance, in non-destructive testing of printed circuit boards (PCBs), perovskite X-ray sensors offer higher-resolution imaging, improving inspection precision and reducing product defect rates.
In semiconductor packaging, with the rise of 2.5D/3D ICs and advanced packaging technologies, there is a growing demand for nanoscale high-resolution X-ray inspection. Perovskite sensors, with their high radiation tolerance and superior imaging resolution, provide a new alternative for semiconductor inspection.
ITRI and InnoCare Optoelectronics have successfully completed module validation for perovskite X-ray sensing technology and are actively promoting its market adoption. Moving forward, the partnership will continue to enhance technological development and integrate AI-powered imaging analysis, expediting automated medical diagnostics. Additionally, as demand for high-throughput X-ray inspection rises, perovskite sensing technology is expected to deliver more efficient and cost-effective solutions for industrial and semiconductor applications.
