Lightweight green polymer materials with exceptional toughness, high strength, and excellent ductility represent ideal candidates for enabling next-generation sustainable flexible electronics. However, the conflicting properties of material strength and toughness present a significant challenge in achieving an optimal combination of both attributes. In this study, a strong yet tough polymeric triboelectric material is prepared by constructing a multiscale reinforced network based on a nonsolvent-induced microphase separation strategy. The synergistic enhancement of strength and toughness is achieved by reinforcing non-covalent interactions within the polymer and constructing nanofibrous networks. The resulting triboelectric materials exhibited remarkable fracture toughness (78.6 MJ m −3 ), high tensile strength (42.5 MPa), an improvement in triboelectric output (71%), and promising recyclability. The integrated triboelectric wearable sensor maintained robust output signals. This study provides a novel solution for coordinating the conflicts between strength and toughness in heterogeneous polymer materials, showing significant potential in expanding their applications in flexible electronics and self-powered sensing technologies.

Non-contact intelligent sensing technology is a key player in the data acquisition and environmental monitoring framework of the Internet of Everything, laying the groundwork for the realization of highly integrated intelligent network systems. However, environmental factors continue to be a major challenge in the process of real-time monitoring and feedback of objects, constraining the stability and accuracy of the sensing signals. In this study, a hierarchical spatial assembly strategy is implemented to effectively integrate an intermediate energy storage layer with superhydrophobic surfaces (CA = 162 ± 2.5°), resulting in the development of a moisture-resistant triboelectric structural materials with stable monitoring and tracking capabilities. The moisture-resistant self-powered sensor constructed from this triboelectric structural material operates effectively in extreme humidity conditions (99% RH) with a full-scale output retention rate of 95.2%, and is capable of accurately sensing human activity from the distance of 3 m. Importantly, the sensor can also effectively detect vehicle states during operation and perform real-time monitoring of the vehicle's surrounding environment. This study not only overcomes the long-standing challenges of accuracy and stability in high humidity for sensors but also advances the development of sustainable, interconnected intelligent systems for the Internet of Everything in extreme environmental conditions.

Lightweight and robust self-powered wearable devices are of great importance in rehabilitation and medical assistance, but this places greater demands on the development of functional materials. In particular, a balance between reducing the weight of materials and enhancing their mechanical performance is urgently needed. Here, this study reports a design strategy based on a cross-scale strengthening mechanism, which endows triboelectric materials with mechanically robust properties, and can withstand more than 16,600 times its weight without any deformation. A biomimetic ordered network structure with “wall-septum” is obtained by using the directional ice templating method, followed by the formation of more hydrogen bonds between polymer molecular chains promoted by salting-out. The resultant triboelectric material exhibits a Young’s modulus of 130.3 MPa, and a specific modulus of 409.0 kN m/kg. Triboelectric materials are used to construct highly robust triboelectric nanogenerators that are stable even under an impact of 735.5 kPa. The accurate acquisition of a human motion state signal in the process of rehabilitation training is realized. This study provides a universal strategy for the development of lightweight and robust triboelectric material and provides a solution for the application of self-powered wearable devices in rehabilitation training.

The water molecules adhering to the surface of the triboelectric layer will take away the surface charge when traditional triboelectric nanogenerators (TENGs) operate in the high-humidity environment, resulting in a reduction in triboelectric performance, which significantly constrains the advancement of TENGs. Herein, a green triboelectric material of chitosan/polyvinyl alcohol longitudinal aerogel film (CP-LAF) with excellent humidity adaptation and triboelectric properties (9 cm 2 , 214 V, 18.25 μA) was prepared by a process of directional freeze-drying assisted mechanical compression with the idea from the anisotropic structure of natural wood. The triboelectric properties of TENGs are enhanced by their layered-ordered porous structure and rough surface. At the same time, it is reusable due to the inherent properties of the components. More importantly, the CP-LAF-based TENG has strong adaptation and stability to a high-humidity environment. Its output voltage at 99 % relative humidity (RH) is 1.6 times that of 50 % RH owing to the triboelectrification involving a large number of water molecules and the increase in the contact area caused by material softening. Additionally, its electrical performance decreases very little after 5000 working cycles. Meantime, it suggests excellent application advantages in energy harvesting and self-powered sensing. This design strategy has the potential to solve the problem of the degradation of traditional triboelectric materials in high-humidity environments. The material provides a stimulating example for the design and preparation of green triboelectric materials that can withstand different humidity environments.

Cellulose-based triboelectric nanogenerators (TENGs) have attracted widespread attention due to the low cost and environmentally friendly characteristics of cellulose. However, achieving high electrical energy output from these generators still presents significant challenges. Here, cellulose is dissolved-regenerated to form a composite aerogel with high specific surface area, in which cellulose-based composites with excellent negative triboelectric properties are developed by coupling the rich 3D network structure of the regenerated cellulose aerogel, modified barium titanate, and poly(vinylidene fluoride). The TENGs assembled from the composite materials exhibit an output voltage of 1040 V and a current of 1.165 mA at an external force of 8 N and a frequency of 4 Hz, outperforming all cellulose-based negative triboelectric materials. In addition, the nanogenerators have a stable electrical energy output capacity, with no significant property degradation in 100 000 contact-separation tests. The excellent electrical output property of the composite materials enables them to harvest energy from human movement and waterdrops, demonstrating their great application prospects in wearable devices, energy harvesting devices, self-powered sensors, and other fields.

Triboelectric sweat sensors, endowed with the technical advantages of non-invasive ex vivo and in situ detection, have catalyzed the rapid advancement of personalized medicine and precision health management systems. However, the inherently low secretion rate and rapid evaporation of sweat pose significant challenges for its efficient collection and rapid analytical screening. This study leverages laser cutting and aqueous interfacial self-assembly strategies to develop a biomimetic heterogeneous wettability triboelectric material (HWTM). Sweat is rapidly collected from the edge to the center of the material, driven by the combined effect of a wettability gradient and the Laplace pressure difference arising from asymmetric curvature at the liquid-solid interface. This collection mechanism markedly enriches target analytes, yielding a signal-to-noise ratio (SNR) of 51 dB, which surpasses that of prevailing sweat sensor technologies. A portable wearable patch is engineered by integrating ion-selective membranes and data processing modules, enabling selective salt ion profiling and real-time wireless monitoring. This work paves the way for the rational design of sweat sensors grounded in fluidic transport mechanisms.

Developing biomass-based triboelectric films with excellent robust and superior tough is crucial for realizing next-generation green, sustainable and flexible wearable sensors. However, simultaneously achieving highly robust and superior tough in biomass-based triboelectric films remains a significant challenge. In this study, inspired by natural creatures, particularly spider silk, based on the structural properties of catechol lignin (C-lignin, CL) and the synergistic effects of nano-confinement and solvent-induced, the robust and tough recyclable C-lignin-based triboelectric films (CNT/CL/PVA film, CCLPF) with a multi-scale reinforcement network was successfully constructed. The prepared lignin-based films exhibited high tensile strength (43.1 MPa, 816%), excellent fracture toughness (512.3 MJ m −3 ), outstanding energy dissipation efficiency (94.9%), superior antibacterial properties, significant antioxidant capacity, and stable triboelectric output performance (245.1 V and 7500 cycles). Notably, a self-powered sensor array is also designed that could accurately perceive pressure distribution changes of different objects, thereby meeting diverse application demands and ultimately providing important technical pathways for the development of wearable devices and human-machine interaction systems. In summary, this study not only offers a novel solution to the conflict between robust and tough in biomass-based triboelectric films but also opens new avenues for the extensive application of lignin resources in flexible electronics and self-powered sensing technologies.

Developing high-performance, wearable electronics that operate reliably in extreme environments is crucial for ensuring life safety, as well as for aerospace and industrial applications. However, existing sensing materials face a trade-off between mechanical performance and high-temperature robustness, limiting their performance gains and stability under heat. This study introduces a thermomechanically robust cellulosic triboelectric material with interfacial nano-bridging that forms a heat-conducting network. Heat-conducting nanosheets and nanotubes intertwine with cellulose through noncovalent interactions. A very small amount of carbon nanotubes (2 wt.%) acts as bridging segments that connect the heat-conducting nanosheets, forming a strong hydrogen-bond network with cellulose to resist energy dissipation during tensile loading. This yields both high mechanical strength (169 MPa) and high thermal conductivity (12.9 W m −1 K −1 ). The performance far exceeds that of most reported polymer composite sensing materials. As a result, self-powered devices based on triboelectric materials maintained stable operation at 230 °C, and achieved a high output power of 2.72 W m − 2 . When integrated into wearable self-powered sensing systems with machine learning, the system achieved a 97% accuracy in motion pose recognition. This work presents a strategy to balance the thermomechanical stability trade-off and provides a general design pathway for sensing materials suitable for complex operating conditions.

The pervasive wearable electronic devices are driving sensor innovation towards increased diversity and multifunctionality , to meet the needs of complex and varied environments. The accuracy of wearable sensors in detecting and feedback on stress is typically contingent upon the responsiveness of material structures , which can be easily perturbed by environmental humidity. In this study, one with excellent hydrophobicity and moisture resistance was developed, thereby effectively suppressing the electrostatic shielding effect caused by water ionization, while retaining the inherent ability of the material surface to generate and capture charges. In high-humidity environments (98 % RH), the self-powered sensor exhibited a full scale output retention rate of over 82.4 %, thus overcoming the limitations of sensor application in such conditions. This study provides new insight into high-performance sensing that is resistant to environmental interference, which is of great significance for the development and design of electronic skin, wearable electronic devices, and soft robotics.

The energy conversion efficiency of a triboelectric nanogenerator (TENG) is severely limited by the charge density of triboelectric materials, while drastic and unavoidable charge decay happens during contact due to the insufficient charge retention capacity of positive triboelectric materials. Here, elaborately synthesized acid-ion-doped pyridine-based polybenzimidazole processing with strong charge retention capability is demonstrated to couple with negatively corona-polarized electrets. As illustrated by thermal stimulation and an ion mass spectrometer, the formation of acid-ion chimerism processes high activation energy for stored charges, and the selective anion migration can compensate the escape of polarized charge. Accordingly, the charge density can reach up to 596 μC m–2 and the charge retention rate reaches 49.7%, which is so far the highest intrinsic charge density obtained in the open air. Thus, the ionic chimerism strategy provides an effective way to suppress the charge escaping in the open air and gives a great expandable avenue for the material challenges of TENG’s practical deployment.

Addressing industrial fluorine waste disposal while enhancing fluorinated triboelectric materials constitutes dual critical challenges. By compounding oxygen-free CaF 2 nanoparticles synthesized from solidified fluoride ions with PVDF, this study achieves simultaneous environmental remediation and triboelectric enhancement. The synergistic mechanisms include: (1) Intrinsic negative triboelectric polarity enhancement (work function increased from 4.97 to 5.31 eV); (2) Aggregated state modulation ( β -phase: 76.8 % to 90.8 %; crystallinity: 43.5 % to 48.9 %); (3) Interfacial polarization (>25 % dielectric constant increase at 1 kHz). The 20 wt% CaF 2 /PVDF composite film exhibits 128 V open-circuit voltage, 43 nC transferred charge, and 403.3 mW/m 2 power density - representing 2.79-fold enhancement over pure PVDF. The composite maintains >95 % output stability through 3000 bending cycles and functions effectively as wearable strain sensors for human motion monitoring. This integrated strategy establishes a sustainable paradigm merging waste valorization with high-performance triboelectric material design.
