Combining traditional textiles with triboelectric nanogenerators (TENGs) gives birth to selfpowered electronic textiles (e-textiles). However, there are two bottlenecks in their widespread application, low power output and poor sensing capability. Herein, by means of the three-dimensional five-directional braided (3DB) structure, a TENG-based e-textile with the features of high flexibility, shape adaptability, structural integrity, cyclic washability, and superior mechanical stability, is designed for power and sensing. Due to the spatial framecolumn structure formed between the outer braided yarn and inner axial yarn, the 3DB-TENG is also endowed with high compression resilience, enhanced power output, improved pressure sensitivity, and vibrational energy harvesting ability, which can power miniature wearable electronics and respond to tiny weight variations. Furthermore, an intelligent shoe and an identity recognition carpet are demonstrated to verify its performance. This study hopes to provide a new design concept for high-performance textile-based TENGs and expand their application scope in human-machine interfacing.

The practical applications of skin-interfaced sensors and devices in daily life hinge on the rational design of surface wettability to maintain device integrity and achieve improved sensing performance under complex hydrated conditions. Various bioinspired strategies have been implemented to engineer desired surface wettability for varying hydrated conditions. Although the bodily fluids can negatively affect the device performance, they also provide a rich reservoir of health-relevant information and sustained energy for next-generation stretchable self-powered devices. As a result, the design and manipulation of the surface wettability are critical to effectively control the liquid behavior on the device surface for enhanced performance. The sensors and devices with engineered surface wettability can collect and analyze health biomarkers while being minimally affected by bodily fluids or ambient humid environments. The energy harvesters also benefit from surface wettability design to achieve enhanced performance for powering on-body electronics. This review first summarizes the commonly used approaches to tune the surface wettability for target applications toward skin-interfaced sensors and devices. By considering the existing challenges, one also discusses the opportunities as a small fraction of potential future developments, which can lead to a new class of skin-interfaced devices for use in digital health and personalized medicine.

Enhanced heat and moisture management has become highly urgent to clothing systems due to the global need to personalize the ventilation process. As a significant sector of apparel industries, membrane‐based clothing systems offer protection and ventilation functionalities. This review aims at providing a new viewpoint on efforts to improve heat and moisture management in membrane‐based clothing systems according to the latest advances in this field. The study terminates with presenting a perspective on current challenges and opportunities for future research directions in personal thermal and moisture management technologies. In fact, membranes with different functionalities used in clothing systems such as photonic membranes with heating and cooling performances, unidirectional liquid transport membranes, waterproof‐breathable membranes, shape‐memory membranes, thermoregulating membranes, thermal conductive membranes and finally protective membranes are investigated. The essential functions associated to different categories of the investigated membranes along with the relationships between membrane structure and properties are presented.
