摘要 ：
The exchange of water between soil and air is a ubiquitous natural phenomenon. Evaporation and condensation are the two main processes that extract or release energy from the environment. However, due to the low energy density and complex interface of soil, the associated energy has long been overlooked and under-exploited. Here we demonstrate that the energy can be converted into electricity in situ through the hydrovoltaic effect within the soil itself. The soil-based hydrovoltaic electricity generators exhibit excellent reproducibility and stability, demonstrating the potential for scalable integration. A series voltage of over 13.4 V was achieved, placing it in the top five of integrated devices reported to date. By designing an integrated module suitable for amplifying natural electricity from both soil evaporation and soil condensation process, a parallel current of up to 18.62 mu A (0.06 m2) was obtained. The availability of soil demonstrates the great potential of the soil-based electricity generators. This finding demonstrates a green and sustainable technology for electricity generation, and points to possible biogeochemical processes due to the hydrovoltaic effect of soil.

摘要 ：
Developing the integration of self-powered detection with both dynamic and static forces is a significant challenge in promoting intelligent technology systems. Herein, we introduce an innovative microbial biofilm basedhydrovoltaic pressure sensor (mBio-HPS) using whole-cell Geobacter sulfurreducens, which successfully combines self-powered functionality and static pressure detection within a single device. The mBio-HPS exhibited a sensitivity of up to 8968.7 kPa-1 (at 1 kPa) in the 0.4-25 kPa regime without external power supply. Moreover, the mBio-HPS demonstrated the fastest reported response speed to date, with a remarkable response time of 112.5 mu s, enabling effective detection of both dynamic and static forces while maintaining stability during an extensive 30,000 s testing. Experimental validation using a sensor-integrated array showed its outstanding realtime detection capabilities for both dynamic and static pressure, highlighting its outstanding potential for electronic skin applications. This unprecedented concept of a hydrovoltaic pressure sensor also offers new insights into the development of high-performance self-powered electronics.

Flexible strain sensors have garnered significant attention due to their high sensitivity, rapid response, and flexibility. Recent innovations, particularly those incorporating machine learning, have significantly enhanced their stability, sensitivity, and adaptability, positioning these sensors as promising solutions in health monitoring, human-computer interaction, and smart home applications. However, challenges remain in optimizing sensor materials for enhanced responsiveness, durability, and stability. Moreover, the development of machine learning-based strain sensors faces obstacles, including algorithmic limitations, low noise tolerance in complex environments, and limited model interpretability. This review systematically evaluates the latest advancements in flexible strain sensors, emphasizing the critical role of machine learning in performance enhancement. It further explores the shift from traditional machine learning methods to deep learning approaches, elucidating the potential applications that these algorithms facilitate. Finally, we discuss future research trajectories, highlighting both opportunities and challenges that may guide the next wave of innovations in this dynamic field.

摘要 ：
Two-dimensional metal-organic framework (2D MOF) materials are emerging as promising candidates for next-generation organic photodetectors due to their high specific surface area, tunable optical properties, superior charge transfer performance, and excellent chemical stability. However, enhancing carrier separation efficiency under illumination and minimizing dark current remain significant challenges in this field. In this study, Zn-TCPP was grown on an ITO substrate, followed by N,N '-dioctyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI-C8), to construct a p-n heterojunction self-powered photodetector. The device exhibits a low dark current of 3.78 pA, a noise equivalent power (NEP) of 9.21 x 10-10 W, and a high specific detectivity (D*) of 4.78 x 1012 Jones at 0 V bias, alongside a fast response time of 15 ms. This work presents an effective strategy for developing high-performance, low-noise 2D MOF-based photodetectors and highlights their potential for use in next-generation wearable optoelectronic devices and imaging systems.

摘要 ：
Bio-hydrovoltaic systems, which leverage the energy embedded in water's natural processes, present a promising avenue for sustainable energy production. Despite notable advances in non-living hydrovoltaic systems, research into biological materials remains relatively underdeveloped, leaving their unique advantages and long-term reliability potential largely untapped. This Review presents a comprehensive synthesis of progress in the field, with a particular focus on the evolution from non-living to living hydrovoltaic systems, and a precise articulation of their conceptual boundaries. We underscore a shift from structure-oriented material engineering toward biofunction-enabled energy conversion-a transition that enables breakthroughs in power output, system durability and environmental adaptability. Through systematic comparisons of mechanisms, biomaterial sources, performance metrics and emerging application scenarios, we identify current bottlenecks and propose targeted strategies. In light of recent trends, living hydrovoltaic systems hold particular promise as a forward-looking direction, offering a transformative platform for future hydrovoltaic internet, intelligence and ecological integration at scale. This Review delineates the conceptual and material transition from non-living to living hydrovoltaic systems, establishing bio-hydrovoltaics as a frontier in sustainable energy conversion from water.

摘要 ：
Memristors, with their intrinsic low power consumption, high speed operation, and unified memory-computing architecture, present a compelling alternative to overcome the limitations of traditional von Neumann systems. However, the instability of single-dielectric-layer memristors, primarily due to the unpredictable formation of conductive filaments, remains a significant challenge. This study presents the design and fabrication of an Ag/Sm2O3(O-D)/Sm2O3(O-R)/Pt/Ti photoelectric memristor with a dual-dielectric layer structure to address these stability concerns. The device exhibits extremely low operation voltages (V-SET: 0.13 V, V-RESET: -0.73 V), a switch window of up to 10(3), and stable performance across 100 consecutive cycles. Leveraging solar-blind UV writing and electrical erasing, this device performs '' OR '' logic operations with nonvolatile and reconfigurable characteristics, using UV and voltage as input signals and resistance states (RS) as output. The results demonstrate that the conduction mechanism is dominated by the conductive filament mechanism, and the dual-dielectric layer significantly improves the stability of the samarium oxide (Sm2O3) memristor. This study provides a potential approach to addressing the stability and longevity challenges in traditional memristors and holds promise for next-generation nonvolatile logic computing devices.
