Emulating brain functionality with neuromorphic devices is an emerging field of research. It is extensively considered as the first step to overcome the limitations of conventional von Neumann systems and build artificial intelligent systems. Currently, most neuromorphic transistors are manufactured on rigid substrates, which are difficult to bend and cannot closely fit soft human skin, limiting their appliction scope. The emergence and evolution of flexible electronic devices address a plethora of application and scenario demands. Particularly, the introduction of flexible neuromorphic transistors injects fresh vitality into neuromorphic computing and perception, symbolizing a significant step towards overcoming the limitations of conventional computational models and fostering the development of more intelligent wearable devices. Herein, the recent developments in felxible neuromorphic transistors are summarized and their applications in neuromorphic computing and artificial perception systems are highlighted. The future prospects and challenges of felxible neuromorphic transistors are also discussed. We believe developments in felxible neuromorphic transistors will shed light on future advances in wearable artificial intelligent systems, humanoid robotics and neural repair technology.

Lithium niobate (LiNbO₃) and lithium tantalate (LiTaO₃) are a class of multifunctional materials with excellent piezoelectric/ferroelectric, electro-optic, and nonlinear optical properties, which have wide applications in high-performance radio frequency filters, optical communications, integrated photonics, quantum information, and other fields. With the advent of the post-Moore era of integrated circuit technology, LiNbO₃/LiTaO₃ thin-film also shows great potential and advantages in new concept chip applications. High-quality single-crystal thin films lay the foundation for high-performance radio frequency, optoelectronic, and quantum devices and their integration. This review first introduces the main characteristics of LiNbO₃/LiTaO₃ single-crystal thin films, such as ferroelectricity, piezoelectricity, electro-optic effect and nonlinear optical effect, then introduces the preparation methods of LiNbO₃/LiTaO₃ single-crystal thin films represented by smart-cut and their application progress in different fields such as waveguides, modulators, laterally excited bulk acoustic wave resonators, and quantum devices. The application prospects and challenges of LiNbO₃/LiTaO₃ single-crystal thin films in post-Moore era chips are also discussed in this article, aiming to provide valuable references for their development and application.
