    217-231页
    查看更多>>摘要：The complex wiring,bulky data collection devices,and difficulty in fast and on-site data interpreta-tion significantly limit the practical application of flex-ible strain sensors as wearable devices.To tackle these challenges,this work develops an artificial intelligence-assisted,wireless,flexible,and wearable mechanolumi-nescent strain sensor system(AIFWMLS)by integration of deep learning neural network-based color data pro-cessing system(CDPS)with a sandwich-structured flex-ible mechanoluminescent sensor(SFLC)film.The SFLC film shows remarkable and robust mechanoluminescent performance with a simple structure for easy fabrication.The CDPS system can rapidly and accurately extract and interpret the color of the SFLC film to strain values with auto-correction of errors caused by the varying color temperature,which significantly improves the accuracy of the predicted strain.A smart glove mechanoluminescent sensor system demonstrates the great potential of the AIFWMLS system in human gesture recognition.Moreover,the versatile SFLC film can also serve as a encryption device.The integration of deep learning neural network-based artificial intelligence and SFLC film provides a promising strategy to break the"color to strain value"bottleneck that hinders the practical applica-tion of flexible colorimetric strain sensors,which could promote the development of wearable and flexible strain sensors from laboratory research to consumer markets.

    Low-Temperature Fabrication of Stable Black-Phase CsPbI3 Perovskite Flexible Photodetectors Toward Wearable Health Monitoring

    232-245页
    查看更多>>摘要：Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy,biomedicine,and sensing fields,but their poor thermal sta-bility hinders further applications.Conversely,all-inorganic perovskites pos-sess excellent thermal stability,but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps,which increases energy con-sumption and is not conducive to the fabrication of flexible wearable devices.In this work,an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reac-tion of diphenylphosphinic chloride additive.The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films,yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 × 1014 Jones.Furthermore,high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors.This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

    265-279页
    查看更多>>摘要：Polymeric microwave actuators combining tissue-like softness with pro-grammable microwave-responsive deformation hold great promise for mobile intelligent devices and bionic soft robots.However,their application is challenged by restricted elec-tromagnetic sensitivity and intricate sensing coupling.In this study,a sensitized polymeric microwave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx(MXene).Compared to the initial counterpart,the hybrid polymer exhibits unique space-charge polarization and interfacial polarization,resulting in significant improvements of 230％in the dielectric loss factor and 830％in the apparent efficiency of electromag-netic energy harvest.The sensitized microwave actuation demonstrates as the shortened response time of nearly 10 s,which is merely 13％of that for the initial shape memory polymer.Moreover,the ultra-low content of MXene(up to 0.15 wt％)benefits for maintaining the actuation potential of the hybrid polymer.An innovative self-powered sensing prototype that combines driving and piezoelectric polymers is developed,which generates real-time electric potential feedback(open-circuit potential of～3 mV)during actuation.The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approach for developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.

    Exploration of Gas-Dependent Self-Adaptive Reconstruction Behavior of Cu2O for Electrochemical CO2 Conversion to Multi-Carbon Products

    Chaoran ZhangYichuan GuQu JiangZiyang Sheng...
    280-296页
    查看更多>>摘要：Structural reconstruction of elec-trocatalysts plays a pivotal role in catalytic per-formances for CO2 reduction reaction(CO2RR),whereas the behavior is by far superficially understood.Here,we report that CO2 accessi-bility results in a universal self-adaptive struc-tural reconstruction from Cu2O to Cu@CuxO composites,ending with feeding gas-dependent microstructures and catalytic performances.The CO2-rich atmosphere favors reconstruction for CO2RR,whereas the CO2-deficient one prefers that for hydrogen evolution reaction.With the assistance of spectroscopic analysis and theo-retical calculations,we uncover a CO2-induced passivation behavior by identifying a reduction-resistant but catalytic active Cu(Ⅰ)-rich amorphous layer stabilized by*CO intermediates.Additionally,we find extra CO production is indis-pensable for the robust production of C2H4.An inverse correlation between durability and FECO/FEC2H4 is disclosed,suggesting that the self-stabilization process involving the absorption of*CO intermediates on Cu(Ⅰ)sites is essential for durable electrolysis.Guided by this insight,we design hollow Cu2O nanospheres for durable and selective CO2RR electrolysis in producing C2H4.Our work recognizes the previously overlooked passivation reconstruction and self-stabilizing behavior and highlights the critical role of the local atmosphere in modulating reconstruction and catalytic processes.

    查看更多>>摘要：High-resolution non-emissive displays based on elec-trochromic tungsten oxides(WOx)are crucial for future near-eye vir-tual/augmented reality interactions,given their impressive attributes such as high environmental stability,ideal outdoor readability,and low energy consumption.However,the limited intrinsic structure of inorganic materials has presented a significant challenge in achieving precise patterning/pixelation at the micron scale.Here,we successfully developed the direct photolithography for WOx nanoparticles based on in situ photo-induced ligand exchange.This strategy enabled us to achieve ultra-high resolution efficiently(line width＜4 μm,the best resolution for reported inorganic electrochromic materials).Addition-ally,the resulting device exhibited impressive electrochromic performance,such as fast response(＜1 s at 0 V),high coloration efficiency(119.5 cm2 C-1),good optical modulation(55.9％),and durability(＞3600 cycles),as well as promising applications in electronic logos,pixelated displays,flexible electronics,etc.The success and advancements presented here are expected to inspire and accelerate research and development(R&D)in high-resolution non-emissive displays and other ultra-fine micro-electronics.

    310-327页
    查看更多>>摘要：Liquid leakage of pipeline networks not only results in considerable resource wastage but also leads to environmental pollution and ecologicalimbalance.In response to this global issue,a bioinspired superhydrophobic thermoplastic polyu-rethane/carbon nanotubes/graphene nanosheets flexible strain sensor(TCGS)has been developed using a combination of micro-extrusion compression molding and surface modification for real-time wireless detection of liquid leakage.The TCGS utilizes the synergistic effects of Archimedean spiral crack arrays and micropores,which are inspired by the remarkable sensory capabilities of scorpions.This design achieves a sensitivity of 218.13 at a strain of 2％,which is an increase of 4300％.Additionally,it demonstrates exceptional durability by withstanding over 5000 usage cycles.The robust superhydrophobicity of the TCGS significantly enhances sensitivity and stability in detecting small-scale liquid leakage,enabling precise monitoring of liquid leakage across a wide range of sizes,velocities,and composi-tions while issuing prompt alerts.This provides critical early warnings for both industrial pipelines and potential liquid leakage scenarios in everyday life.The development and utilization of bioinspired ultrasensitive flexible strain sensors offer an innovative and effective solution for the early wireless detection of liquid leakage.

    Wafer-Scale Ag2S-Based Memristive Crossbar Arrays with Ultra-Low Switching-Energies Reaching Biological Synapses

    328-339页
    查看更多>>摘要：Memristive crossbar arrays(MCAs)offer parallel data storage and processing for energy-efficient neuromorphic com-puting.However,most wafer-scale MCAs that are compatible with complementary metal-oxide-semiconductor(CMOS)technology still suffer from substantially larger energy consumption than biological synapses,due to the slow kinetics of forming conductive paths inside the memristive units.Here we report wafer-scale Ag2S-based MCAs realized using CMOS-compatible processes at temperatures below 160℃.Ag2S electrolytes supply highly mobile Ag+ions,and provide the Ag/Ag2S interface with low silver nucleation barrier to form silver filaments at low energy costs.By further enhancing Ag+migration in Ag2S electrolytes via microstructure modulation,the integrated memristors exhibit a record low threshold of approximately-0.1 V,and demonstrate ultra-low switching-energies reaching femtojoule values as observed in biological synapses.The low-temperature process also enables MCA integration on polyimide substrates for applications in flexible elec-tronics.Moreover,the intrinsic nonidealities of the memristive units for deep learning can be compensated by employing an advanced training algorithm.An impressive accuracy of 92.6％in image recognition simulations is demonstrated with the MCAs after the compensation.The demonstrated MCAs provide a promising device option for neuromorphic computing with ultra-high energy-efficiency.

    Deciphering Water Oxidation Catalysts:The Dominant Role of Surface Chemistry over Reconstruction Degree in Activity Promotion

    Li AnJianyi LiYuanmiao SunJiamin Zhu...
    340-354页
    查看更多>>摘要：Water splitting hinges crucially on the availability of electro-catalysts for the oxygen evolution reaction.The surface reconstruction has been widely observed in perovskite catalysts,and the reconstruction degree has been often correlated with the activity enhancement.Here,a systematic study on the roles of Fe substitution in activation of perovskite LaNiO3 is reported.The substituting Fe content influences both current change tendency and surface reconstruction degree.LaNi0.9Fe0.1O3 is found exhib-iting a volcano-peak intrinsic activity in both pristine and reconstructed among all substituted perovskites in the LaNi1-xFexO3(x=0.00,0.10,0.25,0.50,0.75,1.00)series.The reconstructed LaNi0.9Fe0.1O3 shows a higher intrinsic activity than most reported NiFe-based catalysts.Besides,density functional theory calculations reveal that Fe substitution can lower the O 2p level,which thus stabilize lattice oxygen in LaNi0.9Fe0.1O3 and ensure its long-term stability.Furthermore,it is vital interesting that activity of the reconstructed catalysts relied more on the surface chemistry rather than the reconstruction degree.The effect of Fe on the degree of surface reconstruction of the perovskite is decoupled from that on its activity enhancement after surface reconstruction.This finding showcases the importance to customize the surface chemistry of reconstructed catalysts for water oxidation.
