The scientific communities in both academia and industry are devoted to increasing energy density of supercapacitor devices, including investigating the relationship between carbon structure and capacitance of various activated carbon (AC) materials. However, most reported capacitance values are measured solely at the material level, which are difficult to directly translate into achievable energy densities for practical supercapacitor devices. In this work, we assemble supercapacitor pouch cells to reveal the insight relationships between the capacitance and porosity of AC materials and the optimal amount of electrolyte at the device level. Concurrently, a guidance on the required amount of electrolyte is provided, indicating that both the specific capacitance and porosity of AC materials collectively determine the energy density of a practical device (Edevice). Furthermore, we develop a computational E-tool for directly predicting Edevice at an early stage of material-level electrochemical testing. Finally, we propose a new descriptor (η) that incorporates both the capacitance and porosity parameters of AC materials, which displays a linear relationship with Edevice. This study provides a reliable E-tool and η for accelerating the development of advanced charge storage mechanisms and carbon materials for practical supercapacitor devices.

Health monitoring is becoming increasingly critical for disease prevention, early diagnosis, and high-quality living. Polymeric materials, with their mechanical flexibility, biocompatibility, and tunable biochemical properties, offer unique advantages for creating next-generation personalized devices. In recent years, flexible polymer-based platforms have shown remarkable potential to capture diverse physiological signals in both daily and clinical contexts, including electrophysiological, biochemical, mechanical, and thermal indicators. In this review, we introduce a safety-level-oriented framework to evaluate material and device strategies for health monitoring, spanning the continuum from noninvasive wearables to deeply embedded implants. Physiological signals are systematically classified by use case, and application-specific requirements such as stability, comfort, and long-term compatibility are highlighted as critical factors guiding the selection of polymers, interfacial designs, and device architectures. Special emphasis is placed on mapping material types—including hydrogels, elastomers, and conductive composites—to their most suitable applications. Finally, we propose design principles for developing safe, functional, and adaptive polymer-based systems, aiming at reliable integration with the human body and enabling personalized, preventive healthcare.

Electrochromic smart windows (ESWs) can significantly reduce building energy consumption, but the high cost hinders large-scale production. The in situ growth of tungsten oxide (WO3) films is only by a simple immersion process, the silver nanowires (AgNWs) undergo oxidation to Ag+ ions through electron loss, and the liberated electrons provide driving force for the deposition of WO42−. Enabled the fabrication of large-area WO3 films and ESWs were fabricated under minimal laboratory conditions, demonstrating the economic feasibility, efficient and reliable nature of industrial production. Structural characterization and density functional theory calculations were combined to confirm that AgNWs effectively regulate oxygen vacancies of WO3 films and promote the in situ growth process. The optimized WO3 exhibits a maximum transmittance modulation of 90.8% and excellent cycling stability of 20,000 cycles. The large-scale WO3-based ESWs can save building energy up to 140.0 MJ m−2 compared to traditional windows in tropical regions, as verified by simulations more than 40 global cities. This research provides a new approach for improving the performance and industrial production of ESW, providing the full understanding and development direction to short the distance of the ESW commercial production.
