Organic electronic devices, known for their ultra-thin and flexible properties, are also attracting attention. This study presents a reliable fabrication method for textile-based organic light-emitting diodes (OLEDs) using a parylene-C planarization layer. The process creates a smooth surface with sub-nanometer roughness through a simple transfer and thermal annealing, forming a self-supporting planarization layer without immersion in water or chemicals. The parylene-C film enhances crystallinity and stiffness, ensuring mechanical stability. The fabricated OLEDs operate reliably under extreme deformations such as bending and wrinkling. Additionally, a 3×3 textile-based OLED array was demonstrated for display applications, and a scarf-based OLED verified its potential in fashion. This approach highlights the seamless integration of advanced electronics into textiles, offering promising applications across industries and marking a significant advancement in wearable display technology.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"15 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901456","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}

Here, we introduce tactile sensory nerve systems with biologically realistic energy efficiency, utilizing starfish-inspired capacitive pressure sensors integrated with flexible memristors. These starfish-inspired sensors, with their high aspect ratio (~3) and stress-focusing, hourglass-shaped dielectric microstructures, enable highly sensitive tactile detection across a broad pressure range, effectively mimicking the properties of human skin. Artificial tactile sensory nerves, which integrate the capacitive sensor with a flexible memristor exhibiting synaptic plasticity, function reliably as energy-efficient near-sensor computing systems by bio-realistically transducing mechanical stimuli into transient electrical signals. The developed system operates as both an artificial nociceptor and a tactile near-sensor computing unit, with energy consumption approaching biological levels at approximately 140 pJ and 2.2 fJ, respectively. This neuro-inspired localized computing strategy offers a physical platform for advanced smart user interface applications.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"274 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893600","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, the performance and device area of flexible PeLEDs remains constrained due to issues such as crack formation and short circuits that occur during device deformation. These challenges limit their applicability in flexible, stretchable, and wearable displays and lighting solutions. This review systematically summarizes recent advancements in flexible PeLEDs, focusing on various strategies to improve their flexibility and performance. We first discuss the use of flexible substrates and electrodes in these devices. Next, we examine the fabrication methods and the mechanical and optoelectronic properties of different perovskite materials used in flexible PeLEDs, including three-dimensional (3D) thin films, low-dimensional nanomaterials, and perovskite/polymer composites.

Herein, a series of siloxane coupling agents (SCAs) with different ending groups i.e., –SH, –NH2, and –CN were incorporated at the SnO2/perovskite interface, which can selectively interact with MA+ and Pb2+ via hydrogen and coordination bonding, respectively. It was revealed that the selection of (3-Cyanopropyl)Triethoxysilane (CN-PTES) can regulate perovskite crystallization with accelerated nucleation and retarded crystal growth, leading to improved crystallinity with released residual lattice strain. Moreover, the incorporated CN-PTES aligned the energy structure of the underlying SnO2 and boosted the interfacial adhesion between perovskite and SnO2, resulting in facilitated electron extraction and enhanced interfacial fracture energy. Consequently, the first screen-printed f-PSCs with improved mechanical resistance were finally obtained.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"14 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822499","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 graphene-Au nanomembrane features a bond-free van der Waals interface, allowing the Au layer move freely with graphene. This structure mitigates the formation of cracks, enhancing the stretchability to over 14% strain and fatigue resistance. Moreover, this composite overcomes the limitations associated with skin depth, consequently enabling an ultra-thin graphene-Au antenna operating at 8.5 GHz for 5 G communications.

However, further power reductions are crucial for wearable systems with limited onboard power, and achieving sufficient signal strength at minimal luminance is essential for extended operation. Here, we propose an OPO structure with both ultralow power consumption and low luminance operation.
