Potential for integrated flexible electronics has been shown for 2D materials with atomically thin layers and dangling‐bond‐free surfaces. Strain engineering is a fascinating technique for tuning or controlling the electronic and optical properties of 2D materials. In the review article, an effort to condense the most recent and promising approaches that can be used to create flexible nanoelectronic and optoelectronic devices in the future and expand their range of useful applications is made. In order to investigate their electrical behavior, the majority of the devices are created using chemical vapor deposition (CVD) or mechanical exfoliation of ultrathin 2D TMD materials. This makes it possible to develop flexible piezo‐phototronic photodetectors, self‐powered sensors, and wearable and implantable devices with higher strain tolerance. On the basis of 2D TMDs materials, a comparison of the performance and characteristics of 2D flexible electronic devices is also carried out. In order to advance the development of wearable and implantable electronics with greater strain tolerance for health monitoring and usher in a new era of flexible technologies, this overview of recent research on 2D flexible electronics based on nanomaterials is intended to aid in the advancement of the field. Finally, it summarizes the current challenges and opportunities.

With an emphasis on remarkable properties, twisted vertical heterostructures have received particular attention in experimental and theoretical works. They have promising unknown effects in science and technology. These twisted systems can be considered a platform for the formation of crystalline film structures. In this paper, we consider one of them, diamond-like crystals with Moiré atomic structure formed from twisted two-dimensional hexagonal layers. Analogues of carbon Moiré diamanes are nanometer-thick films obtained by both stacking and twisting near 30° of two functionalized monolayers of nitrides (AlN, BN, GaN), which have already been actually obtained. We study their energetically stable atomic configurations and electronic and elastic properties. The proposed hydrogenated and/or fluorinated (second side, Janus structures) Moiré nitridane nanostructures with a twisted angle of 27.8° possess a wide band gap from 3 to 4 eV. Electronic band structures are characterized by many flattened bands located near the edges of the valence and conduction bands, which tend to be signatures of Moiré superlattices. The Moiré nitridanes can be used as a base for two-dimensional semiconductors with low-dispersive flattened bands and strong localization of the electronic states, which should increase the probability of their resonant IV characteristics and light excitations. Thus, the circumstance is useful for nano- and optoelectronic resonant devices. In addition, it was found that hydrogenated and fluorinated Moiré nitridane and nitride films have some very different elastic responses, which are attractive for mechanoelectric applications.
