Highlights
A 2.5-dimensional dynamic structural color based on nanogratings of heterogeneous materials was proposed by interweaving a pH-responsive hydrogel with IP-L photoresist.
The nanogrid structures exhibit brilliant tuneable structural color, high sensitivity, and ultrafast recovery speeds in response to pH.
The 4D printing-based grayscale design approach was proposed for the patterned encoding and array printing of dynamic structural colors, promoting their application in patterned printing, information encryption, and microfluidic chip sensing.

Highlights
A double-layered protective film based on zinc-based coordination compound and ZnF2-rich solid electrolyte interphase layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic optimization.
The double-layered architecture can effectively modulate Zn2+ flux and suppress the zinc dendrite growth, thus facilitating the uniform zinc deposition.
The as-developed zinc-(dual) halogen batteries based on double-layered protective film can present high areal capacity and satisfactory cycling stability.

Despite the promising progress in conductive hydrogels made with pure conducting polymer, great challenges remain in the interface adhesion and robustness in long-term monitoring. To address these challenges, Prof. Seung Hwan Ko and Taek-Soo Kim’s team introduced a laser-induced phase separation and adhesion method for fabricating conductive hydrogels consisting of pure poly(3,4-ethylenedioxythiophene):polystyrene sulfonate on polymer substrates. The laser-induced phase separation and adhesion treated conducting polymers can be selectively transformed into conductive hydrogels that exhibit wet conductivities of 101.4 S cm−1 with a spatial resolution down to 5 μm. Moreover, they maintain impedance and charge-storage capacity even after 1 h of sonication. The micropatterned electrode arrays demonstrate their potential in long-term in vivo signal recordings, highlighting their promising role in the field of bioelectronics.
尽管使用纯导电聚合物制造导电水凝胶取得了可喜的进展，但在界面粘附性和长期监测的稳健性方面仍存在巨大挑战。为了应对这些挑战，Seung Hwan Ko 教授和 Taek-Soo Kim 的团队引入了一种激光诱导相分离和粘附方法，用于在聚合物基底上制造由纯聚（3,4-亚乙二氧基噻吩）：聚苯乙烯磺酸盐组成的导电水凝胶。经激光诱导相分离和粘附处理的导电聚合物可选择性地转化为导电水凝胶，其湿电导率为 101.4 S cm-1，空间分辨率低至 5 μm。此外，即使经过 1 小时的超声处理，它们仍能保持阻抗和电荷储存能力。微图案电极阵列证明了它们在长期体内信号记录方面的潜力，凸显了它们在生物电子学领域大有可为的作用。

Highlights
Vertical 1D GaN nanorod arrays/2D MoS2/PEDOT:PSS heterostructures in wafer scale have been fabricated for flexible photodetection firstly.
Self-powered flexible photodetector at compressive strain reveals a significantly enhanced photoresponse with a responsivity of 2.47 A W−1 and response times of 40/45 µs, which are superior to the state-of-the-art flexible devices.
This work not only provides a valuable strategy for the design and construction of tunable van der Waals heterostructures, but also opens a new opportunity for flexible sensors.
由低维（0D、1D 和 2D）材料构建的范德华（vdW）异质结构正在成为下一代柔性光电探测中最具吸引力的系统之一。目前，手工堆叠的 vdW 型光电探测器与大面积阵列制造不兼容，而且在自供电模式下表现平平。本文首次提出了晶圆级垂直一维 GaN 纳米棒阵列（NRAs）/二维 MoS2/PEDOT:PSS 自供电柔性光电探测器阵列。得益于 GaN NRAs 的强光吸收和 II 型异质结中高效的光生载流子分离，该集成器件在弱紫外光照射下无需外部偏压，便可实现 1.47 A W-1 的高响应率和 1.2 × 1011 Jones 的高探测率，以及 54/71 µs 的快速响应速度。值得注意的是，该器件的应变可调光电探测性能已得到证实。令人印象深刻的是，该器件在-0.78%应变和零偏压条件下的光响应显著增强，响应率为2.47 A W-1，探测率为2.6 × 1011 Jones，响应时间为40/45 µs，优于最先进的自供电柔性光电探测器。这项工作为制备自供电柔性光电探测的可调 vdWs 异质结构提供了一条宝贵的途径，它在柔性传感器中表现出色。

Highlights
The large-scale, high-strength, super-tough, and multifunctional nacre-like heterocyclic aramid (HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite papers were fabricated using the in-situ assembly of PPy onto the HA/MXene hydrogel template.
The "brick-and-mortar" layered structure and abundant hydrogen-bonding interactions among MXene, PPy, and HA respond cooperatively to external stress and effectively increase the mechanical properties of HMP nanocomposite papers.
The templating effect from HA/MXene was utilized to guide the assembly of conducting polymers, leading to high electrical conductivity and outstanding electromagnetic interference shielding performance.

The rising flexible and intelligent electronics greatly facilitate the noninvasive and timely tracking of physiological information in telemedicine healthcare. Meticulously building bionic-sensitive moieties is vital for designing efficient electronic skin with advanced cognitive functionalities to pluralistically capture external stimuli. However, realistic mimesis, both in the skin’s three-dimensional interlocked hierarchical structures and synchronous encoding multistimuli information capacities, remains a challenging yet vital need for simplifying the design of flexible logic circuits. Herein, we construct an artificial epidermal device by in situ growing Cu3(HHTP)2 particles onto the hollow spherical Ti3C2Tx surface, aiming to concurrently emulate the spinous and granular layers of the skin’s epidermis. The bionic Ti3C2Tx@Cu3(HHTP)2 exhibits independent NO2 and pressure response, as well as novel functionalities such as acoustic signature perception and Morse code-encrypted message communication. Ultimately, a wearable alarming system with a mobile application terminal is self-developed by integrating the bimodular senor into flexible printed circuits. This system can assess risk factors related with asthmatic, such as stimulation of external NO2 gas, abnormal expiratory behavior and exertion degrees of fingers, achieving a recognition accuracy of 97.6% as assisted by a machine learning algorithm. Our work provides a feasible routine to develop intelligent multifunctional healthcare equipment for burgeoning transformative telemedicine diagnosis.
