Here, we present a solvent-mediated solid-liquid interface doping strategy to engineer vertically phase-separated (VPS) PEDOT: PSS films. By adjusting thickness and doping solvents, a thicker PEDOT: PSS film with a strong VPS structure was achieved, featuring a higher PSS/PEDOT ratio on the surface and a lower ratio at the bottom. Doping the pristine film with a metastable liquid-liquid contact solution enables gradual PSS migration and a significant component gradient, yielding films with a hydrophilic surface and one of the highest reported conductivities ( ~ 8800 S cm−1) for bioelectronic devices. The films patterned by laser processing present high-fidelity signal acquisition, and excellent electrochemical stability. With low impedance and long-term biocompatibility, they are employed for real-time wearable and implantable sensors for electrophysiological monitoring, showcasing broad potentials in bioelectronics and human–machine interactions.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"12 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640397","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 synergism between ionic conductivity, tailored metal-nitrogen interaction, and fabric porosity enables the sensor with high response (R0/Rg = 14.7 towards 1 ppm NH3), low detection limit (36 ppb), and remarkable selectivity (coefficient >5.12 against common organic interferents). Notably, the optimized sensor yields a sixfold enhancement in response as compared with traditional EC-MOF powders. A linear regression model validated by fivefold cross-validation achieves 98.4% accuracy in NH3 concentration prediction, while the kNN classifier shows 96% accuracy in gas identification (tested on 192 samples). Preliminary clinical tests show that the sensor can clearly differentiate the exhaled NH3 signals of four patients with HE from those of healthy individuals, demonstrating the potential for non-invasive diagnostics.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"44 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611171","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}

Meanwhile, synaptic characteristics were induced by gradual charge trapping via optical pulse stimulation. Synaptic plasticity was confirmed via the potentiation–depression curve, emulating key features of biological nervous system, namely short-term memory (STM) and long-term memory (LTM). Furthermore, the fingerprint recognition tasks highlighted identification and authentication abilities by incorporating our synaptic function into an artificial neural network (ANN). The dual-mode memory transistor, fabricated on a business card, showed excellent compatibility with flexible optoelectronics, maintaining stable memory and synaptic performance over 500 bending cycles with minimal changes in memory window, memory ratio, and potentiation–depression behavior.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"694 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602881","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}

Their surface property differences prevented reliable stretching-tolerant connections. Here, we report a universal method to construct stretchable connections based on interfacial covalent reactions. It enables robust and conductive bonding among various soft/rigid electronics through simple surface modification and interfacial reaction. The bonding between SEBS rubber and metals reached stretchability over 250% with interfacial toughness over 200 N/m. The ultrathin connection layer provided conductive pathways, achieving an electrical stretchability of 60% between Au-deposited SEBS and Cu sheets. Connections between liquid metal-based stretchable conductors could withstand more than 10,000 stretching cycles to 60% strain while maintaining their high conductivity. The versatility and stability of this method were further proved by fabricating electronic devices that integrated soft and rigid units, including circuits on papers and a gesture-visualizing glove with LEDs, highlighting the robustness of the stretchable connections.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"82 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586861","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}

Standard neural probes carrying the microelectrodes are rigid silicon-based structures that can penetrate the brain parenchyma to interface with the targeted neurons. Unfortunately, within weeks after implantation, neural recording quality from microelectrodes degrades, owing largely to a neuroinflammatory response. Key contributors to the neuroinflammatory response include mechanical mismatch at the device-tissue interface and oxidative stress. We developed a mechanically-adaptive, resveratrol-eluting (MARE) neural probe to mitigate both mechanical mismatch and oxidative stress and thereby promote improved neural recording quality and longevity. In this work, we demonstrate that compared to rigid silicon controls, highly-flexible MARE probes exhibit improved recording performance, more stable impedance, and a healing tissue response. With further optimization, MARE probes can serve as long-term, robust neural probes for brain-machine interface applications.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"8 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594189","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, previously developed biodegradable conductive fibers often suffered from incomplete degradability, limited flexibility, and scalability. Here, we introduce a biodegradable, flexible, and mass-producible fiber electrode, consisting of tungsten microparticles, a polybutylene adipate-co-terephthalate matrix and a poly butanedithiol 1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione pentenoic anhydride coating. The dry-jet wet-spinning process ensures uniform filler dispersion and continuous fiber formation, yielding high conductivity (~2500 S m−1) over lengths exceeding 10 m. The coating provides flexibility (~38% strain) and durability against repeated deformation and laundering. We demonstrate wearable textile electronics by integrating fiber-based temperature sensors, electromyography electrodes, and a wireless coil into an arm sleeve. Finally, enzymatic and soil biodegradation tests highlight their potential as sustainable and eco-friendly disposable electronics.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"21 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578123","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}
