Foldable electroluminescent (EL) devices have attracted much attention in recent years. By folding, 2D EL devices can be transformed to 3D structures, which play an important role in foldable, portable, and 3D displays. Foldability is similar to flexibility, but there are differences. Foldable electronic devices mainly focus on the properties of the folding regions, which are flexible or stretchable, while the non‐folding regions may be rigid. On the other hand, folding deformation is usually accompanied by severe and sharp compression and stretching in the folding regions, which have a significant impact on device performance. The unique deformation characteristics make foldable devices complicated in materials, structures, and strategies. In this review, the progress of foldable electronic devices is summarized. According to the crease characteristics, foldable devices are divided into a free‐folding type and a crease‐preset type. First, the materials, structures, and strategies of various non‐luminescent foldable electronic devices are summarized, which will enlighten the research of foldable EL devices. Then, the progress of foldable EL devices is summarized. Foldable EL devices are still in the early stage of research and still face many problems and challenges. It is hoped that this review can promote their rapid development.

In recent years, there has been immense advancement in the development of nanobiosensors as these are a fundamental need of the hour that act as a potential candidate integrated with point-of-care-testing for several applications, such as healthcare, the environment, energy harvesting, electronics, and the food industry. Nanomaterials have an important part in efficiently sensing bioreceptors such as cells, enzymes, and antibodies to develop biosensors with high selectivity, peculiarity, and sensibility. It is virtually impossible in science and technology to perform any application without nanomaterials. Nanomaterials are distinguished from fine particles used for numerous applications as a result of being unique in properties such as electrical, thermal, chemical, optical, mechanical, and physical. The combination of nanostructured materials and biosensors is generally known as nanobiosensor technology. These miniaturized nanobiosensors are revolutionizing the healthcare domain for sensing, monitoring, and diagnosing pathogens, viruses, and bacteria. However, the conventional approach is time-consuming, expensive, laborious, and requires sophisticated instruments with skilled operators. Further, automating and integrating is quite a challenging process. Thus, there is a considerable demand for the development of nanobiosensors that can be used along with the POCT module for testing real samples. Additionally, with the advent of nano/biotechnology and the impact on designing portable ultrasensitive devices, it can be stated that it is probably one of the most capable ways of overcoming the aforementioned problems concerning the cumulative requirement for the development of a rapid, economical, and highly sensible device for analyzing applications within biomedical diagnostics, energy harvesting, the environment, food and water, agriculture, and the pharmaceutical industry.

[44][45][46][47] To produce an integrated foldable RFEH system within a single sheet of paper containing an RF antenna, RF/DC rectifier, and an energy storage unit (e.g., an SC), it is essential to improve its conductivity, RF patterning, cost-effectiveness, and mechanical stability. However, the RF antenna requires stable electrode patterning, high conductivity with a sheet resistance under 1 Ω sq −1 , and a homogeneous substrate, which could be provided by coated paper, but a foldable RFEH system also requires mechanical stability such as flexibility and foldability, which is possible with nanopaper.…”

deep sea, underground, chemical plants, environmental disasters areas, and agricultural farmland. [7] Radio frequency energy harvesting (RFEH) has emerged as a promising option for powering IoTbased devices due to the broad availability of radio frequency (RF) signals, which, despite their relatively low energy density, are accessible in places where other energy sources such as solar and thermal energy are unavailable or limited. [8][9][10] However, conventional RFEH systems have limitations in terms of their cost, size, weight, and foldability. As a result, many studies have attempted to combine novel fabrication methods and ambient RFEH to produce low-cost, light, small, and foldable power supply systems. [11][12][13][14] Cellulose paper is a promising substrate for the fabrication of RFEH systems that satisfy these requirements. Paper has recently gained significant attention as a component of electronics due to its abundance, disposability, recyclability, biocompatibility, light weight, cost-effectiveness, and flexibility. [15][16][17] Based on these advantages, paper or paper-like substrates have been utilized in a variety of applications ranging from basic electronic units to complicated electronic devices such as supercapacitors (SCs), [18,19] light-emitting diodes (LEDs), [20] transistors, [21] biofuel cells, [22] RF antenna, [23] and sensors. [24] However, it remains difficult to employ conventional methods for the fabrication of paper-based electronics in the development of integrated foldable RFEH systems that incorporate an RF antenna, RF/direct current (DC) rectifier, and energy storage unit. The main reason for this is the limitations associated with paper when seeking to fabricate a stable electrode due to its high porosity, hygroscopy, and surface roughness. [15] In general, the porosity and surface roughness of a substrate are important properties affecting the quality of a fabricated electrode because they can affect ink or particle penetration continuity and disrupt conductive paths if they are too high. [25] As a result, the roughness and porosity of paper substrates for electronic applications need to be reduced. [26,27] In particular, because RF electronics require a more stable and homogeneous substrate and higher conductivity than DC components, [28,29] untreated paper is generally not suitable for RF electronics. In addition, the hygroscopic nature of conventional paper hinders the complicated patterning required for RF electronics, such as the fabrication of uniform micro-sized lines, vias, and conductive patterning on both sides of paper. Radio frequency energy harvesting (RFEH) systems have emerged as a critical component for powering devices and replacing traditional batteries, with paper being one of the most promising substrates for use in flexible RFEH systems. However, previous paper-based electronics with optimized porosity, surface roughness, and hygroscopicity still face limitations in terms of the development of integrated foldable RFEH systems within a single sheet of paper....
