Here, another and yet unexplored class of materials, cosmetic materials, have been reported, where nail-paints (NPs) have been investigated as the active layer of the TENG. The constituents of NP, nitrocellulose and various aromatic plasticizers, impart tribo-positive character to the resultant film. In vertical contact separation mode, NP-TENG produces an open-circuit voltage of ∼120 V and short-circuit current of ∼12 µA with an aluminum layer, which increases to ∼400 V and ∼40 µA, respectively, with polydimethylsiloxane as the negative layer. With NP-TENGs, energy is harvested seamlessly by drawing a layer of nail paint in any shape, colour, or pattern, which can be quickly modified to any other variant. Performance of NP-TENGs is remarkably resistant against water immersion, oil application, sand contamination, temperature, and bending. With simple paint-and-produce processing, NP-TENGs are a highly facile and accessible option for harvesting energy anytime and anywhere, where assembling and disassembling of TENG is as prompt as application and removal of nail-paint for beautification.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"84 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a novel flexible bimodal sensor is architected for the synchronous perception of tactile pressure and bioelectrical signals. The core of the tactile sensing unit is a capacitive pressure sensor, which synergistically integrates a cold‐pressing microstructured poly(vinylidene fluoride‐hexafluoropropylene) [P(VDF‐HFP)] dielectric layer with compressible carbon fabric (CF) electrodes. This composite structure achieves exceptional compressibility and controlled micro‐gaps, enabling an ultrahigh and broad‐range sensitivity of 0.221 kPa −1 (0–8 kPa) and 14.11 MPa −1 (65–240 kPa). Impressively, the CF electrode also establishes low‐impedance epidermal coupling, which is critical for high‐fidelity bioelectrical sensing. This capability is confirmed through clear electrocardiogram (ECG) traces with distinct PQRST peaks and a high signal‐to‐noise ratio (SNR) of 21.66 dB (curling) and 12.50 dB (gripping), which are comparable to those obtained with a commercial bioelectrode. The practical utility of the integrated system is further demonstrated through real‐time dexterous control of a robotic hand and the machine learning‐assisted transmission and decryption of a doubly‐encrypted Morse code communication system. This work establishes a new design paradigm for multifunctional sensing interfaces toward next‐generation intelligent systems.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multi-cellular architecture recapitulates hepatic organization by spatially positioning endothelial and parenchymal compartments in physiologically relevant arrangements, enabling paracrine signaling, enhanced nutrient exchange, and stable cell–cell/matrix interactions. Integrated with a dynamic microfluidic perfusion system, the construct supports matrix remodeling, delivers physiological shear stress, and sustains a well-oxygenated microenvironment. Compared to static culture, dynamic perfusion preserved long-term albumin and urea secretion, enhanced cytochrome P450 activity, reduced oxidative stress, and maintained mitochondrial integrity over extended culture periods. Transcriptomic profiling confirmed significant enrichment of metabolic, junctional, and drug-processing pathways. Functionally, the multi-cellular platform demonstrated robust and inducible drug-metabolizing capacity, enabling accurate identification of clinically relevant hepatotoxic compounds. Drug potency metrics—including IC50 and benchmark dose values—closely matched reported human plasma concentration thresholds, underscoring the translational potential of the system.

Here, we present a general strategy to enhance the toughness of single‐network (SN) injectable hydrogels by incorporating flexible polyethylene glycol (PEG) chains into a rigid hyaluronic acid (HA) framework, termed framework–flexible (FF) hydrogels. This design simultaneously increases network homogeneity and introduces chain‐length contrast for efficient energy dissipation. As a result, the optimized FF hydrogel achieves a 7‐fold increase in compressive strength and a 4‐fold increase in compressive toughness compared with its corresponding PEG‐free SN counterpart. In addition, the hydrogels exhibit excellent fatigue resistance and tunable mechanical properties while maintaining outstanding biocompatibility. This general approach provides a practical and powerful tool for developing tough, clinically compatible, and easily deployable injectable hydrogels.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"17 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their performance is severely limited by high defect densities and pronounced instability. Herein, we report the successful fabrication of high-performance NIR photodetectors based on an inverse opal (IO) photonic crystal structure of formamidinium tin iodide (FASnI3) perovskite. This structural design significantly reduces the defect density of the Sn-based perovskite functional layer and markedly enhances its stability. Notably, a bifunctional organic additive, 1,4-butanediammonium iodide (BDADI), plays a key role in enabling the formation of perovskite IO structures by effectively regulating the colloidal chemistry and crystallization kinetics of FASnI3. The resulting ordered BDADI-modified FASnI3 (FASnI3-BDADI) IO architecture not only enhances light harvesting via slow-photon effects but also facilitates efficient carrier transport. As a result, the IO photodetector achieves record-breaking responsivity (5.90 A·W−1) and a champion detectivity (1.06 × 1014 Jones) at 808 nm, along with excellent unencapsulated stability attributed to the lotus effect of photonic crystal.

Here, we use nonlinear 2D-THz spectroscopy to scrutinize the dynamics arising from the nonlinearities of the EIT-like phenomenon in a metamaterial platform comprising two coupled resonators. From the temporal profiles of the nonlinear pump-probe and photon-echo signals, we found that the bright mode relaxation time is almost twice the time for the coherent exchange of energy between the two coupled resonators. The multi-peak nature of the photon-echo signal and the corresponding temporal signatures further provide a direct visualization of the interference between the dressed states that drives the transparency window in our THz metamaterial. A time-resolved density-matrix model accurately describes the observed features, including the cross-peak behavior and the temporal dynamics, establishing the coherent mode coupling as the origin of the transparency window.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"10 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
