Here, we present a passive osmotic differential electrochemical (PODE) patch for continuous, non‐invasive L‐Dopa monitoring under resting conditions. The patch employs an ethylene glycol‐loaded polyacrylamide/polyvinyl alcohol (PAAm/PVA) hydrogel as a “chemical osmotic pump” to drive sweat transport without external power or physical exertion. For sensitive detection, a three‐dimensional paper‐based electrode is constructed via in situ growth of acrylamide‐doped poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and gold nanoparticles (AuNPs). To eliminate interferences from uric acid (UA) and ascorbic acid (AA), a tyrosinase‐enabled dual‐channel differential sensing strategy is employed. The sensor exhibits a wide linear range and maintains high selectivity in complex artificial sweat. By seamlessly integrating passive sampling with interference‐rejecting electrochemical detection, this flexible, low‐cost patch offers a practical and user‐friendly platform for personalized, at‐home management of PD.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most nano‐piezoelectric catalysts' catalytic efficiency in biosafety and biocompatibility is unsatisfactory. Herein, this study modifies the typical piezoelectric material tetragonal barium titanate (T‐BTO). It introduces novel manganese (Mn) ‐coated T‐BTO nanoparticles (MCTB) that possess magnetic resonance imaging (MRI) ability and enhanced PCT effects. The encapsulation of Mn masks the piezoelectric effect of the nanoparticles, and the acidic tumor microenvironment (TME) triggers the stripping of Mn and restoration of the piezoelectric effect of T‐BTO, which produces ROS under ultrasonic irradiation. The presence of Mn ions also enhances the MRI property of the tumor site as a contrast agent. Additionally, ultrasonic irradiation promotes the conversion of low‐valence Mn into a high‐valence state, further stimulating ROS production. The biosafety, therapeutic effects, T1‐weighted MRI, and piezoresponse of MCTB are investigated in vitro. Animal studies also indicate that the nanoparticles display good treatment performance when activated by ultrasound and guided by MRI. Therefore, this study develops an MCTB particle that boosts ROS generation, enables tumor‐specific ROS release, and enhances T1‐weighted MRI, offering a safe PCT approach for tumors.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"11 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Superstructures addressing this challenge have hitherto been fabricated on relatively intricate, still‐fragile routes, which stability remains a critical concern. Herein, biomimetic nanoporous brochosome carbons (BCs) with microporous quasi‐superstructure were successfully prepared using a unique hard template‐SiO 2 brochosome microspheres (SiO 2 BMs). By simply adjusting the ratio of CTAB containing SiO 2 BMs and the polydopamine (PDA), the microstructure of microporous quasi‐superstructure on the hollow wall of BCs could be fine‐turned. The obtained BCs exhibit selective heteroatom doping and localized carbonization surrounding the regularly arranged micropores, achieving an optimized impedance matching and significantly enhances the capture and dissipation of incident microwaves. Notably, BC‐2.0 shows a minimum reflection loss ( RL min ) of −54.33 dB and an ultra‐broad maximum effective absorption bandwidth ( EAB max ) of 8.85 GHz at a thickness of 2.90 and 2.89 mm, covering the full Ku‐ and X‐bands, respectively, without any magnetic particles.

However, current research for microrobot design and actuation predominantly focuses on aqueous and physiological fluid environments, and thus effective ways for driving microrobots to operate in viscous oil‐based media remains are still limited. To address this issue, we develop an acoustic magnetic hybrid microrobot leveraging bubble and fin structures for acoustic propulsion as well as magnetic coating layer for controlled navigation. With acoustic stimuli, the microrobot can achieve 2–6 mm/s motion speed propelled by the oscillating bubble. With magnetic steering, the microrobot can be controlled to move along arbitrary paths. Experimental results demonstrate that the microrobot can rapidly and accurately navigate to target locations in oil environments. Secondary acoustic radiation forces can capture target particles with different sizes, then transport them to target location and release. The proposed acoustic‐magnetic hybrid manipulation strategy enables microrobots to operate in viscous oil environments, offering a new paradigm to unlock the environment adaptability for complex application scenarios.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"11 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional graphene oxide (GO) devices suffer from strongly bound water and high through‐thickness diffusion resistance, leading to slow recovery and pronounced hysteresis. Here we report a 3D sulfonated GO (S‐GO) self‐powered flexible humidity sensor. Introducing sulfonic groups with higher hydrophilicity and polarity enables proton generation at low relative humidity and rapid recombination during drying. The electrostatic repulsion induced by sulfonation slightly enlarges and homogenizes the interlayer spacing, and, together with a 3D interconnected framework, forms low‐tortuosity pathways for water transport. These features jointly shorten response and recovery times and markedly reduce hysteresis. The device operates without external bias and produces a stable voltage under humidity perturbations, exhibiting excellent cycling stability. We further demonstrate that the sensor can distinguish different breathing patterns. The proposed S‐GO architecture offers a promising materials‐and‐structure route toward fast, low‐hysteresis, and stable humidity sensing for flexible wearables and human‐machine interaction.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/admt.202502304","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, prolonged use may cause severe side effects, necessitating sensitive detection methods. Conventional techniques often suffer from complexity, signal interference, and a lack of real‐time capability. This study develops molecularly imprinted 2D photonic hydrogels (DSP/BSP‐MIPH) for selective, sensitive, and regenerable detection of DSP and BSP. The DSP‐MIPH sensor exhibits swelling in DSP solution, enabling linear detection in three ranges (0.1–9, 10–100, and 100–1000 µ M ) with a limit of detection (LoD) of 41 nM. BSP‐MIPH shows shrinkage upon binding, with linear responses in 0.05–1 and 5–1000 µ M ranges and a LoD of 28 n M . The limits of quantitation are 1.2 µ M and 146 n M for DSP and BSP, respectively. The opposite volume changes stem from distinct hydrogen bonding interactions between drug functional groups and the hydrogel network. The sensors successfully quantify DSP and BSP in commercial injections, achieving recovery rates of 96.7%–109.5% for DSP and 97.9%–104.8% for BSP, with RSDs 3.91%–6.21% for DSP and 3.57%–5.76% for BSP.

The hierarchical micro/nanostructure and low surface energy of the PM‐CPPS coating significantly enhanced its hydrophobicity (WCA > 157°), and the photothermal effect enabled complete melting of surface ice within 93 s. Experimental results showed that at −15°C, the coating extended the freezing time of water droplets by approximately 20‐fold.

Typical smart glove solutions with flexible sensors can only recognize discrete gestures, not sentences, and fail to meet the daily communication needs of signers. Moreover, current interfaces for displaying recognition outcomes are mostly confined to smartphones or computers, limiting seamless communication between signers and non‐signers. Herein, we propose an artificial intelligence hand gesture recognition HMI system consisting of an intelligent sensing glove, a machine learning module, and a virtual reality interface. This system represents a substantial leap forward in gesture recognition technology with adaptability, comfort, and lightweight construction. Enhanced by advanced machine learning algorithms, it achieves remarkable accuracy across a diverse range of gestures—including 10 numeric gestures, 14 alphabetic phrases, and 5 sentence patterns—boasting 99.5% accuracy for numeric and 99.3% accuracy for alphabetic recognition and an impressive 98.8% accuracy for sentence‐level interpretation. The system projects recognition results into a virtual space, translating gestures into text in real time.
