The 2D electrodes were created via a screen-printing method with an omnidirectional pre-stretching strategy, while 3D array-structured electrodes were formed through electrostatic actuation. Nano-MnO2 and Na0.77MnO2 were deposited to enhance pseudo-capacitive storage and widen the electrochemical window. The C-C/MnO2-based MSCs exhibited a 21% pseudo-capacitance ratio, achieving an area-specific capacitance of 118.2 mF cm−2 at 5 mV s−1 and an energy density of 39.25 mWh cm−2 at 0.21 mW cm−2. These MSCs maintained 95.05%, 92.04%, and 89.74% of their capacitance under stretched, twisted, and folded conditions, respectively, and showed stable performance across temperatures from −20 °C to 60 °C. Additionally, C-C/Na0.77MnO2-based MSCs extended the electrochemical window to 1.6 V and retained 100.2% capacitance after 6500 cycles. This work offers innovative strategies for advancing portable and wearable electronic devices.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"665 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144534025","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 channel ink was formulated by dispersing ZnO nanoparticles with a small amount of hydroxyl-rich ethyl cellulose in terpineol, which converted into a semiconducting film at a low temperature of 90 °C. The paper-based transistor arrays exhibited desirable electrical properties, large-area uniformity, environmental stability and biodegradable, making them particularly promising as disposable devices. The printed ZnO synaptic transistors demonstrated exceptional photoelectric synaptic behaviors, including paired-pulse facilitation and depression, high-pass and low-pass filtering, learning, forgetting, relearning, Morse code recognition, and short-term/long-term plasticity, all at a low energy consumption of about 3.7 pJ per synaptic event. Artificial visual learning and information storage capabilities were achieved owing to the persistent photoconductance effect of the printed ZnO films, achieving an accuracy of 91.4% in neuromorphic computing through optoelectronic co-modulation.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"44 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288502","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}

In this work, we introduce a novel PEDOT:Sacran bio-nanocomposite as a channel material for flexible and biodegradable OECTs. Sacran, a high-molecular-weight polysaccharide derived from blue-green algae, possesses exceptional ionic conductivity, water retention, and biocompatibility, making it a promising candidate for bioelectronic applications. We successfully fabricated ultrathin and flexible OECTs on poly(ethylene terephthalate) (PET) foils, achieving transconductance values up to 7.4 mS. The devices exhibited stable ion-to-electron transduction after mechanical deformation. The OECTs were further demonstrated on eco-friendly and biodegradable poly(lactic acid) (PLA) substrates, achieving a transconductance of 1.6 mS and undergoing enzymatic hydrolysis under controlled conditions. This study highlights the potential of Sacran-based conductive bio-nanocomposites in advancing sustainable bioelectronic devices.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"21 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278575","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}

This mechanical gradient is crucial for applications such as rotator cuff and Achilles tendon repair patches, which prevent stress shielding and ensure uniform stress distribution, addressing the stress concentration issues common in traditional repairs. Here, we present a strategy that achieves high strength even at high water content, enabling programmable modulus/structural gradients with broad applicability. Using rotator cuff tendon repair as a model system, we demonstrate successful in vivo tissue regeneration with integrated real-time sensing capabilities, providing quantitative data for rehabilitation protocols. The hydrogels exhibit precisely controlled regional mechanical properties and seamless interface transitions, mimicking the hierarchical structure of native tissue. This approach not only improves healing outcomes compared to conventional methods but also establishes a quantitative standard for rehabilitation training.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"5 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237069","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, conventional skin electronics often rely on rigid materials and expensive fabrication processes, limiting flexibility and skin-adhesion. In this study, we developed cellulose nanofiber (CNFs)-based adhesive electronics by integrating a three-dimensional octopus-inspired architecture (OIA) and a conductive layer. The OIA imprinted on CNFs enhanced adhesion by leveraging the synergistic effect of its adhesive structure and the ability to remain stable even after absorbing active ingredient solutions. Unlike conventional fiber-based TDD platforms, the optimized CNFs-OIA retains its architecture, enabling suction-based adhesion to improve skin attachment. To further enhance the TDD efficiency, we integrated a conductive layer into the CNFs-OIA. This conductive interface generates microcurrents that reduce the electrical resistance of the stratum corneum and facilitates the ionization of active ingredients, thereby improving skin penetration.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"19 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237513","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 device features a 3D architecture integrating embedded microfluidics with multilayer thermoelectric networks, providing improved heat exchange capacity suitable for high thermal design power (TDP) requirements. The device achieves ~10 °C environmental and 11 °C on-skin temperature reduction with precise control. Furthermore, by integrating a temperature sensor and control circuit with the 3D TED, a wearable closed-loop system is developed. Benefiting from the improved device performance and advanced control algorithms, this system enables accurate and rapid regulation of skin temperature, demonstrating potential applications in virtual temperature and pain sensation.
