Flexible fiber batteries, an essential component of wearable technology, hold the promise of significant progress with the development of high-safety zinc-manganese (Zn-Mn) fiber batteries. To counteract the issues of inadequate electrochemical performance and low voltage of Zn-Mn fiber batteries, we present a dual-strategy featuring a unique composite hydrogel electrolyte and a cathode-less design. The electrolyte, with a reinforced-concrete structure, optimizes the interaction with Zn 2+ ions, accelerating Zn 2+ ion transport, and suppressing HER and Zn dendrite growth. The resulting fiber batteries offer an outstanding energy density of 227.08 mWh cm −3 , double that of the reported Zn-ion fiber batteries, with a high capacity of 156.48 mAh cm −3 and 76.5 % retention after 2700 cycles. The cathode-less design enhances the deposition/dissolution of Zn 4 SO 4 (OH) 6 · x H 2 O, boosting the operating voltage to 1.9 V. The fiber batteries exhibit excellent adaptability, maintaining operation after washing or cutting, and they integrate seamlessly into textiles for a health tracking system, marking a significant advancement in smart fabric technology for wearable devices.

Natural muscles feature resilient actuation, but currently developed artificial muscle fibers do not. The main challenge is serious plastic elongation, especially when artificial muscle fibers are operated at heavy loads, significantly limiting their applications. We report a resilient artificial muscle fiber that deploys an elastic sheath. The sheath enables full lengthwise recovery of the coiled artificial muscle fiber straightened at 375% strain. This muscle fiber produces natural muscle-like resilient actuation, which features elastic elongation when bearing heavy loads and consistent contractions at load-balanced muscle lengths. Two muscle fibers connected in an antagonistic structure, amounting to ∼8% of the weight of an electrical rudder system, efficiently control the flight attitude of a commercial ornithopter. An adaptive pressure band based on these muscle fibers provides rhythmic pressure to prevent venous diseases. Such resilient muscle fibers can offer important potential in robotics and wearable technologies that require high durability and adaptability.

Wearable technology is experiencing remarkable progress, prompting the need for sustainable power sources like triboelectric nanogenerators (TENGs). However, integrating TENGs into fabrics and insufficient power outputs that allows for comfortable wear without obstructing user's movements presents a significant challenge. In this study, a novel kind of diamond-structured fabric-based triboelectric nanogenerators (DSF-TENGs) is introduced utilizing an easy, economical, and scalable weaving method without any chemical modification. Owing to its 3D diamond pattern, surface interactions are enhanced for greater charge generation together with strengthened mechanical engagement for more effective charge transfer. The DSF-TENG, with its unique self-resilient structure, achieves impressive electric performance, including output voltage of ≈763 V, short-circuit current of ≈20.4 µA, and power density of 2862.78 mW m −2 , which is multiple times higher than most existing fabric-based TENGs. It also offers excellent air permeability of 560 mm s −1 , consistent electricity generation and sensing even after ten washing cycles, and incredible durability, withstanding over 30 000 cycles. Furthermore, DSF-TENG is included in an insole that is capable of sensing gait patterns, walking speed, and fall detections of patients with Parkinson's disease. The remarkable power generation capabilities of DSF-TENG indicate a strong potential for future developments in wearable electronics and healthcare applications.

Displays are basic building blocks of modern electronics 1 , 2 . Integrating displays into textiles offers exciting opportunities for smart electronic textiles—the ultimate goal of wearable technology, poised to change the way in which we interact with electronic devices 3 , 4 , 5 , 6 . Display textiles serve to bridge human–machine interactions 7 , 8 , 9 , offering, for instance, a real-time communication tool for individuals with voice or speech difficulties. Electronic textiles capable of communicating 10 , sensing 11 , 12 and supplying electricity 13 , 14 have been reported previously. However, textiles with functional, large-area displays have not yet been achieved, because it is challenging to obtain small illuminating units that are both durable and easy to assemble over a wide area. Here we report a 6-metre-long, 25-centimetre-wide display textile containing 5 × 10 5 electroluminescent units spaced approximately 800 micrometres apart. Weaving conductive weft and luminescent warp fibres forms micrometre-scale electroluminescent units at the weft–warp contact points. The brightness between electroluminescent units deviates by less than 8 per cent and remains stable even when the textile is bent, stretched or pressed. Our display textile is flexible and breathable and withstands repeated machine-washing, making it suitable for practical applications. We show that an integrated textile system consisting of display, keyboard and power supply can serve as a communication tool, demonstrating the system’s potential within the ‘internet of things’ in various areas, including healthcare. Our approach unifies the fabrication and function of electronic devices with textiles, and we expect that woven-fibre materials will shape the next generation of electronics.

Phase change materials (PCMs) have gained significant interest in personal thermal management technologies owing to high latent heat capacity and isothermal phase transitions. However, achieving simultaneous thermal and wearing comfort remains a formidable challenge due to their solid rigidity and liquid leakage. In this work, a polyetheramine-based conductive phase change film was developed by introducing ion transport network and tetradecanol as phase change components encapsulated within the skeleton network. The film possesses adjustable heat storage density (79.5–163.4 J/g) and exceptional flexibility at room temperature. On the basis of desirable thermal regulation ability and ideal wearability, the film was successfully applied in the personal thermal management field and effectively regulated the human body temperature. Moreover, the film realized human motion sensing and object tactile recognition in real time with construction of the inner ion transport channels. This successful exploration provides a promising and scalable route towards intelligent wearable thermal management.

Alternating current electroluminescent (ACEL) fibers with wearable characteristics, such as flexibility, light weight, stitchability and comfort, are emerging in textile displays for daily applications. To construct efficient ACEL fibers, a judiciously designed and low-cost electrode is also extremely important but seems to receive less attention. Inspired by fiber dyeing, we propose a method that employs non-noble metals to design fiber electrodes by constructing microconductive channels inside commercial fibers. This method relies on the window period formed by the glass transition temperature of the PAN fibers, which is sufficiently flexible to extend to mass production at a low cost (approximately US$ 1.86/kg). The resulting ACEL fibers interwoven with a transparent fiber electrode formed a textile display with an acceptable luminescence performance of 46 cd · m −2 (160 V). Notably, a visual feedback e-textile (VFET) was constructed by integrating fiber sensors, which demonstrates the concept of wearable real-time visual monitoring and interaction. Compared with their individual counterparts, VFET has been conveniently and efficiently for visual monitoring, communication, and interaction, i.e., the visualization of physiological parameters (heartbeat, respiration, etc.) and nonverbal communications (literal or cryptographic) for special groups and specific scenes.

Wearable thermoelectric generators (TEGs) have exhibited great potential to convert the temperature gradient between the human body and the environment into electrical energy for maintenance-free wearable applications. A 2D planar device structure is widely employed for fabricating flexible TEGs due to its simple structure and facile fabrication properties. However, this device configuration is more appropriate for utilizing in-plane temperature differences than the out-of-plane direction, which limits their application in wearable cases since the temperature difference between the human body and the environment is in the out-of-plane direction. To solve this problem, a novel fabric-based TEG structure that can utilize the out-of-plane temperature gradient is proposed in this work. By introducing thermally conductive components in the generator, the out-of-plane temperature difference can be switched to the in-plane direction, which can be further utilized for 2D planar devices in wearable applications. The prepared thermoelectric fabric prototype with only 12 p-type TE legs exhibits a maximum open-circuit voltage of 4.69 mV and an output power of 39.7 nW at a temperature difference of 30 K. This strategy exhibits a high degree of versatility and can be readily applied to other 2D planar TEGs, thus expanding their potential application in wearable technology.

The escalating demand for energy harvesting technologies to power small wireless devices has intensified interest in triboelectric nanogenerators (TENGs), yet challenges in energy conversion efficiency and durability persist. In this study, we present a novel core-shell BaTiO 3 @P(VDF-TrFE) nanofiber (BT@PVFT NF) structure, developed to enhance the triboelectric performance of TENGs for wearable and portable electronic applications. The BT@PVFT NF were fabricated using coaxial electrospinning , combining the high dielectric constant of BT with the ferroelectric properties of PVFT to maximize surface charge density and energy conversion efficiency. The morphological, structural, and phase characteristics of the BT@PVFT NFs were thoroughly investigated, with significant findings on the enhancement of the β-phase of PVFT through the synergistic effects of the core-shell configuration and electrospinning process . The optimized TENG demonstrated remarkable electrical output, achieving peak output voltage of 450 V and power density of 80 μW cm −2 , alongside exceptional durability over 15,500 cycles. Furthermore, the device successfully powered commercial electronics and exhibited robust mechanical energy harvesting from human motion. This work not only advances the understanding of core-shell structures in energy harvesting but also highlights the potential of the BT@PVFT NFs for self-powered sensing applications, opening new pathways for the development of energy-efficient wearable technologies .

Piezoelectric sensors are critical components in advancing smart electronic devices, offering significant potential for energy harvesting and self-powered applications in flexible and wearable technologies. Poly(vinylidene fluoride) (PVDF) and molybdenum disulfide (MoS 2 ) are recognized for their exceptional piezoelectric properties, with monolayer MoS 2 effectively enhancing the piezoelectric response. This study innovatively fabricates PVDF/MoS 2 composite films via electrospinning, directly inducing polar β -phase crystal formation in PVDF and significantly enhancing piezoelectric performance. Furthermore, PVDF micro- and nanoparticles were electrostatically deposited onto the PVDF/MoS 2 films, resulting in a P-PVDF/MoS 2 composite with enhanced mechanical and piezoelectric properties. Under a mechanical force of 3 N at 2 Hz, the fabricated sensor achieved an output voltage of 5 V, a short-circuit current of 0.08 μA, and a power density of 3.5 mW/m 2 , representing increases of 552% in voltage, 33% in current, and 192% in power density compared to pure PVDF sensors. The highly flexible composite demonstrates significant potential as a wearable self-powered sensor and energy harvester, addressing applications in artificial intelligence and wireless technologies.

Developing fabric-based electronics with good wearability is undoubtedly an urgent demand for wearable technologies. Although the state-of-the-art fabric-based wearable devices have shown unique advantages in the field of e-textiles, further efforts should be made before achieving “electronic clothing” due to the hard challenge of optimally unifying both promising electrical performance and comfortability in single device. Here, we report an all-fiber tribo-ferroelectric synergistic e-textile with outstanding thermal-moisture comfortability. Owing to a tribo-ferroelectric synergistic effect introduced by ferroelectric polymer nanofibers, the maximum peak power density of the e-textile reaches 5.2 W m −2 under low frequency motion, which is 7 times that of the state-of-the-art breathable triboelectric textiles. Electronic nanofiber materials form hierarchical networks in the e-textile hence lead to moisture wicking, which contributes to outstanding thermal-moisture comfortability of the e-textile. The all-fiber electronics is reliable in complicated real-life situation. Therefore, it is an idea prototypical example for electronic clothing.

Flexible sensors with a single tactile sensing function have been extensively studied, however, the development of highly sensitive multifunctional sensors remains a significant challenge in the realm of wearable technology. In this paper, a multifunctional flexible capacitive sensor with integrated proximity, pressure and temperature perception is developed. The dielectric layer of the sensor is obtained by spontaneous polymerization of polyvinyl alcohol and the ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide at room temperature. The electrode structure is optimized by leveraging the capacitive fringing field effect, and the designed hole-circle shaped 4 × 4 electrode array achieves optimal proximity sensitivity with a maximal capacitance drop of 0.54 pF to human hand and a detection distance of 30 mm. Besides, the prepared microcone structure sensor exhibits high pressure sensitivity of 4.822 kPa-1(0-5 kPa), rapid response time (<100 ms), a broad detection range (~200 kPa), and excellent stability over 3000 cycles of loading/unloading tests. By exploiting the temperature dependence of the ionic liquid, the sensor also exhibits high temperature sensitivity of 80.6%°C-1(25-80°C). Finally, we verified the successful application of this sensor in dynamic finger trajectory recognition, multi-touch and robotic grasping state detection, paving the way for its use in artificial intelligence, healthcare, and intelligent robotics.

In recent years, low-cost wearable energy storage devices attract much more attention. In this work, the PET/CuS/PPy composite electrodes are fabricated for portable flexible solid-state supercapacitors (FSSC), originating from the insulating PET fabric substrate. In this occasion, the functional layer of copper sulfide (CuS) are designed and chemically deposited on the insulating PET fabric to synchronously develop its dual functions such as high electrical conductivity and large capacitance. As a result, the PET/CuS/PPy electrode shows a high specific capacitance of 5410 mF cm–2 at 2 mA cm–2 and good cyclic stability (retaining 84.1% after 2000 cycles). This excellent recyclable specific capacitance is ascribed to the outstanding homogenous binder-free conductive morphologies of CuS and PPy, forming the rapid electronic and ionic transfer channels. Especially, the synchronous dual functions of CuS including high electrical conductivity and large capacitance play a more important role in the large specific capacitance. The flexible solid state supercapacitor (FSSC) also bears a superior specific capacitance of 1335 mF cm–2 (10.1 F cm–3) at 2 mA cm–2 and an outstanding energy density of 1.4 mW h cm–3 at the power density of 8.4 mW cm–3, together with fine flexibility and cyclic stability. Four serially connected FSSC devices can easily supply the electric power for LED indicator lights, calculators, and electric fans, indicating the prospective practical applications in portable flexible energy storage devices. This work provides a facile approach to develop the synchronous dual roles of CuS, which will have the extensive applications in wearable flexible E-textiles.
