In this paper, a flexible deep sea tactile sensor is reported, capable of detecting object's conductivity, hardness, pressing pressure and position simultaneously just by one touch. The sensor works by using single‐walled carbon nanotubes doped thermoplastic polyurethane elastomer (SWNTs‐TPU film) for differentiating object's conductivity based on the work function difference induced electron transfer. A porous anionic aliphatic waterborne polyurethane film containing carboxyl functional groups (C‐WPU) is used for generating ionic currents under pressing to determine the pressing pressure and position and recognize the relative hardness of an object. It is found that the magnitude of current signal generated by a metallic object is much larger than that of an insulative object. The signal magnitude increases with the increase in the applied pressure, the pressing area and the film thickness. Furthermore, completely encapsulating the C‐WPU film and introducing carboxylic functional groups significantly improve the sensitivity (maximum 1.2 kPa−1). The response time and recovery time of sensing signals are 150 and 530 ms respectively. A pressure detection range of 45–625 kPa is achieved, with a pressure detection resolution of 9.2 kPa. The signal magnitude is decreased only by 10.54% when the sensor is placed under a simulated 100 m water depth. Proof of concept demonstration of underwater object discrimination and hardness recognition with this sensor placed on a mechanical finger of a ROV (Remotely Operated Vehicle) is successfully achieved. This work provides a new solution for multi‐modal tactile information sensing in deep‐sea environment.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"90 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503666","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}

Most of the interface‐modified materials can be dissolved due to the highly polar nature of the perovskite precursor solution, thereby compromising the scalability and long‐term stability of the devices. Here, an organic molecule is introduced to modify the buried interface between SnO2 and perovskite, and demonstrated that the solubility and the functional moieties are of great significance for constructing a benign buried interface. Besides, effective chemical bridging between the SnO2 and perovskite layers endorses suppressed defects, better crystallinity, and reduced energy loss. Consequently, the best‐performing PSCs obtain a power conversion efficiency of 25.08% and excellent on‐shelf and photo‐stability (according to the ISOS stability protocols).

This work demonstrates a tailored interface treatment combined with multifunctional surface coatings that significantly enhance the efficiency and lifetime of GaAs/GaInP tandem cells capable of unassisted solar water splitting. In particular, it is shown that exposure of the top AlInP window layer to a remote H2 plasma effectively reduces the interfacial oxide, enhancing charge extraction and maximizing the available photovoltage. Subsequent atomic layer deposition (ALD) of a bilayer coating comprising a TiO2 corrosion protection layer and Pt nanoparticles enhances the durability of the device, enables efficient electron extraction, and provides high catalytic activity. By tuning the Pt ALD process, a nanoparticulate morphology is achieved, ensuring high catalytic activity at low loading, thus minimizing parasitic light absorption and improving adhesion. The optimized dual‐junction photoelectrode achieves an initial maximum solar‐to‐hydrogen (STH) conversion efficiency of 17.1%, stabilizing at 16.2% for 170 min of continuous operation.

This study systematically investigates imprint‐induced operational deviations in 2‐bit/cell HfAlOx ferroelectric capacitors, revealing significant coercive voltage shifts within minutes at room‐temperature that substantially compromise intermediate state re‐writing accuracy. First‐order reversal curve analysis quantitatively resolves the imprint‐generated internal electric field distribution, while impedance spectroscopy and X‐ray photoelectron spectroscopy identify charged oxygen vacancies as the dominant imprint mechanism. Phase‐field simulations further unveil how internal electric fields alter domain switching dynamics through temporally advanced and retarded polarization reversal, directly explaining the distorted hysteresis behavior and intermediate state re‐writing failures. To mitigate this critical issue, a pre‐programming protocol enabling controlled oxygen vacancy charge redistribution is developed, achieving precise intermediate states programming under room‐temperature operation.

The conductance enhancement at the SHO/BLSO interface is measured as a function of the thickness of the SHO layer and the La doping rate in the BLSO layer. A monotonic increase of conductance as a function of the SHO thickness is observed, unlike the case of polar interfaces of LaInO3/BaSnO3 and LaScO3/BaSnO3. The first several unit cells of SHO have the most significant impact on conductance. It is also found that the SHO/BLSO interface requires little doping (≈0.2%) to compensate for the deep acceptors in BaSnO3. To determine the charge carrier distribution, capacitance–voltage profiling is employed, which indicates that the charge carriers are confined within 1–2 nm of the interface. The observed 2D electron gas behavior at the interface is analyzed using a self‐consistent Poisson‐Schrödinger equation solver. This analysis provides a consistent picture of the SHO thickness and the La‐doping dependence of conductance enhancement at the SHO/BLSO interface, suggesting that the large conduction band offset at the SHO/BLSO interface and the intrinsic deep donor states in SHO are responsible for formation of a potential well in the BLSO side.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"246 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503661","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}
