“…As mentioned in the previous sections, OFETs have been widely used for fundamental studies and have been applied in electronics, photonics, and biological fields. [56,76,430] Mechanically flexible OFET-based sensors are promising candidates for commercial (portable) applications since their OSC materials show flexibility, molecular design suitable for modification, roomtemperature and low-power operating requirements, cost-effectiveness, and solution processability. OFETs allow, for instance, the production of low-cost wearable or on-skin diagnostic systems for point-of-care approaches.…”

According to the forecast of Allied Market Research, the flexible electronics market is projected to reach $42.48 billion by 2027. It is estimated to revolutionize the lighting technology, power integration displays, and health monitoring systems. The popularity of flexible electronics is mainly due to the unique benefits of organic materials and devices that offer cost-effectiveness, low-temperature processability, mechanical softness, and shape adaptability, [5][6][7] which are difficult to obtain with traditional, complementary-metal-oxide-semiconductor (CMOS)-based rigid systems. [8] Over the past two decades, research interest in flexible electronic systems has grown exponentially, driven by the requirements of interface softness and shape adaptability for electronics used in Internet-of-Things (IoT), [9] human-machine interfaces, [10] and advanced healthcare. [11] Although significant progress has been made in academia, the practical application of flexible electronics in the industry is limited. Presently, thin-film photovoltaics and flexible displays mainly contribute to the flexible electronics market, with a noticeable presence held by radio frequency identification (RFID) tags and medical X-ray imagers. [12] Indeed, much of the success of present flexible electronic systems rely on the performance and reliability of thin-film The development of flexible and conformable devices, whose performance can be maintained while being continuously deformed, provides a significant step toward the realization of next-generation wearable and e-textile applications. Organic field-effect transistors (OFETs) are particularly interesting for flexible and lightweight products, because of their low-temperature solution processability, and the mechanical flexibility of organic materials that endows OFETs the natural compatibility with plastic and biodegradable substrates. Here, an in-depth review of two competing flexible OFET technologies, planar and vertical OFETs (POFETs and VOFETs, respectively) is provided. The electrical, mechanical, and physical properties of POFETs and VOFETs are critically discussed, with a focus on four pivotal applications (integrated logic circuits, light-emitting devices, memories, and sensors). It is pointed out that the flexible function of the relatively newer VOFET technology, along with its perspective on advancing the applicability of flexible POFETs, has not been reviewed so far, and the direct comparison regarding the performance of POFET-and VOFET-based flexible applications is most likely absent. With discussions spanning printed and wearable electronics, materials science, biotechnology, and environmental monitoring, this contribution is a clear stimulus to researchers working in these fields to engage toward the plentiful possibilities that POFETs and VOFETs offer to flexible electronics.

“…[63] With the rising of the artificial intelligence to break the von Neumann computing structure, the new optoelectronic chips containing synapsis, memory, and logical operation features have attracted great attentions. [226][227][228][229] Furthermore, the new concept "metaverse" are highlighted by Facebook, giving an explosive growth in the need of the more compatibility, complexity integrated devices for building the full virtual feeling of the dynamic digital world. The retino-morphic photonic chips photon alleviate the back-end image processing and signal transmission decay, which is crucial for intelligent bionic application.…”

2D materials possess superior optoelectronic properties, such as ultrahigh mobility and broadband photoresponse, making them one of the most vital platforms for diversified photodetectors. However, atomic thickness 2D materials usually suffer from intrinsic low absorption. To promote the photo detector performance, a feasible method is to integrate the 2D materials with lowcost, flexible, and tunable organics that form a charge transfer (CT) heterojunction. As results, indepth multifunctional CT 2Dinorganic/organic detector exhibits extended functions such as lowpower consumption, in memory detection, and opticalbio synapse to meet the demand of contem porary photonic cell. Particularly, the progresses in waferscale monocrystal of both 2D and organic materials render vast potential applications with operation frequencies ranging from ultraviolet to terahertz. Here, the recent advances of 2Dinorganic/organic CT photodetectors are comprehensively reviewed by several classifications. Future developments and applications in optical biology, synapsis, and machine vision are also highlighted.

The ongoing global COVID‐19 pandemic, caused by the SARS‐CoV‐2 virus, has resulted in significant loss of life since December 2019. Timely and precise virus detection has been proven as an effective solution to reduce the spread of the virus and to track the epidemic. Rapid antigen diagnostics has played a significant role in the frontline of COVID‐19 testing because of its convenience, low cost, and high accuracy. Herein, different types of recently innovated in‐lab and commercial antigen diagnostic technologies with emphasis on the strengths and limitations of these technologies including the limit of detection, sensitivity, specificity, affordability, and usability are systematically reviewed. The perspectives of assay development are looked into.
