“…2D semiconducting materials have attracted increasing attention because of their good semiconductor properties and superior mechanical characteristics. [63,[564][565][566][567] Transition-metal dichalcogenides (TMDs), such as MoS 2 , WS 2 , TaSe 2 , MoSe 2 , NbSe 2 , NiTe 2 , and Bi 2 Te 3 , have received lots of attention for their potential in large-scale printed flexible electronics. [63,449,[568][569][570] The indirect bandgap of some TMDs, such as MoS 2 and MoSe 2 , will change into a direct bandgap when reduced to a single layer.…”

Human-integrated devices include wearable and implantable devices for monitoring vital human signals or interacting with the human body. [1-3] The human-integrated devices needed to be tethered to the organs or the human skin for implementing their functions such as sensing and energy harvesting. [4-18] The economical, agile, customizable manufacturing, and integration of multifunctional device modules into networked systems with mechanical compliance and robustness will enable unprecedented human-integrated smart wearables [19-23] and usher in exciting opportunities in emerging technologies such as electronics, [24-29] wearable computation, [30-36] human-machine interface, [37-42] robotics, [43-48] and advanced healthcare. [49-54] The fabrication of stateof-the-art microelectronics involves hightemperature processing steps, which are generally incompatible with the flexible substrates (e.g., paper, polymer, fiber, etc.) [55-61] widely used in the wearable devices. Moreover, the current microfabrication technologies are not well positioned to process the emerging functional nanomaterials (e.g., nanowires [NWs] and 2D materials). [62-65] Such incomparability severely limits the pace of deploying these emerging materials (despite their unprecedented properties) in wearable and flexible device technologies. The additive manufacturing (AM) processes have emerged as potential candidates for addressing the earlier limitations of the current microfabrication technologies in fabricating flexible/wearable printed devices with diversified functionalities, e.g., energy harvesting/storage, sensing, actuation, and computation, leveraging advantages such as maskless processing, versatile ink formulation, low cost, low processing temperature, and scalability. [66-71] Researchers have devoted tremendous efforts to develop the related technologies, and several reviews have provided excellent discussions on the material formulation and process aspects of AM techniques. [63,72-79] However, to our best knowledge, there are few review reports about the ink-based additive nanomanufacturing of functional materials for human-integrated smart wearables. To fill this gap, here we review the recent progress in ink-based

“…Instead of the rigid-integrated silicon-based semiconductors, nanotechnology points out a new way towards inorganic flexible devices, which is to buffer the macroscopic deformation by the relative movement of numerous boundaries. At present, the thin-film device constructed by two-dimensional (2D) materials represents one of the most promising candidates [ 5 ]. However, the fatigue and phonon scattering at grain boundaries are still unsolved issues [ 6 ].…”

With increasing research interest in the field of flexible electronics and wearable devices, intensive efforts have been paid to the development of novel inorganic-organic hybrid materials. As a newly developed two-dimensional (2D) material family, MXenes present many advantages compared with other 2D analogs, especially the variable surface terminal groups, thus the infinite possibility for the regulation of surface physicochemical properties. However, there is still less attention paid to the interfacial compatibility of the MXene-organic hybrids. To this end, this review will briefly summarize the recent progress on MXene-organic hybrids, offers a deeper understanding of the interaction and collaborative mechanism between the MXenes and organic component. After the discussion of the structure and surface characters of MXenes, strategies towards MXene-organic hybrids are introduced based on the interfacial interactions. Based on different application scenarios, the advantages of MXene-organic hybrids in constructing flexible devices are then discussed. The challenges and outlook on MXene-organic hybrids are also presented.

“…2 Over the past decade, flexible electronics has attracted worldwide and increasing attention in various areas of science, engineering, and technology. [3][4][5][6][7] Despite the success, such devicelevel flexibility derived by using flexible substrate is inherently restricted by the mechanical characters of the semiconductor used in the device. It is desirable if the semiconductor (the functional component) is as intrinsically flexible/deformable as the substrate to comply with the device deformation, making device more robust and adaptive.…”

Flexible electronics ushers in a revolution to the electronics industry in the 21st century. Ideally, all components of a flexible electronic device including the functional component shall comply with the deformation to ensure the structural and functional integrity, imposing a pressing need for developing roomtemperature strain-tolerant semiconductors. To this end, there is a long-standing material dilemma: inorganic semiconductors are typically brittle at room temperature except for size-induced flexibility; by contrast, organic semiconductors are intrinsically soft and flexible but the electrical performance is poor. This is why the discovery of bulk plasticity in Ag 2 S at room temperature and ZnS in darkness is groundbreaking in solving this long-standing material dilemma between the mechanical deformability and the electrical performance. The present review summarizes the background knowledge and latest advances in the emerging field of plastic inorganic semiconductors. At the outset, we argue that the plasticity of inorganic semiconductors is vital to strain tolerance of electronic devices, which has not been adequately emphasized. The mechanisms of plasticity are illustrated from the perspective of chemical bonding and dislocations. Plastic inorganic materials, for example, ionic crystals (insulators), ZnS in darkness, and Ag 2 S, are discussed in detail in terms of their prominent mechanical properties and potential applications. We conclude the article with several key scientific and technological questions to address in the future study.
