“…[2] The innovative X-ray detectors, ideally envisaged to be tractable, cost-effective, portable, and flexible, are not only readily processed into a large area, but can also be fitted into nonplanar application scenarios. [3] Indeed, the current flat panel detectors suffer from a phenomenon called vignetting in nonplanar scenarios, and consequently, multiple X-ray exposures are employed for ensuring imaging quality. Unfortunately this represents a significant potential radiation risk to human bodies.…”

Semiconductive metal-organic frameworks (MOFs) have emerged in applications such as chemical sensors, electrocatalysts, energy storage materials, and electronic devices. However, examples of semiconductive MOFs within flexible electronics have not been reported. We present flexible X-ray detectors prepared by thermoplastic dispersal of a semiconductive MOF (SCU-13) through a commercially available polymer, poly(vinylidene fluoride). The flexible detectors exhibit efficient X-ray-to-electric current conversion with enhanced charge-carrier mobility and low trap density compared to pelleted devices. A high X-ray detection sensitivity of 65.86 mCGy air À1 cm À2 was achieved, which outperforms other pelleted devices and commercial flexible X-ray detectors. We demonstrate that the MOF-based flexible detectors can be operated at multiple bending angles without a deterioration in detection performance. As a proof-of-concept, an X-ray phase contrast under bending conditions was constructed using a 5 5 pixelated MOF-based imager.

Ever‐increasing demand for a healthy and sustainable life has been a traditional motivation behind state‐of‐the‐art medicines and precision diagnosis tools. Nowadays, the ultra‐connectivity and data‐centric initiatives that underpin the future Internet of Things is seen as another major driver of electronically enriched, highly customizable healthcare platforms. Especially, the information display technology, which already enjoys its position as an all‐round player in consumer electronics is poised to broaden its territory by envisioning a range of bio‐related features. In this review, the rising opportunities for next‐generation display‐based biotechnology and healthcare systems are critically assessed in light of recent literature. Clearly, smart combination of new materials, devices, and integration strategies has given rise to highly promising prototypes, and this article aims at highlighting some of these examples. Despite such progress, it is still unclear whether the resultant technologies will make a measurable impact in the near future, given both their own scientific limits and the lack of proper business model. In this regard, the final part of this contribution is dedicated to emergent challenges as well as development solutions that this potentially disruptive innovation may need to consider.
