However, current firefighter garments are limited by their singular functionality and cannot collect or analyze body fluid during rescue missions. Here, we introduce a wetting gradient effect assisted ultrasensitive meta-garment that incorporates multi-signal biomonitoring, offering an early warning system for heat exhaustion risk. This design enables real-time detection of heart rate, pH value, and the concentrations of glucose, sodium, and potassium in sweat. Benefiting from the surface energy difference, gradient wettability surfaces can be formed, allowing for precise point-to-point fluid control and regulation. Thus, the biosensing fibers require the lowest detection volume (0.1 μL) and fastest response time (1.4 s) reported to date. This innovative garment provides a practical solution for early health warning based on abnormal multi-biomarker changes, representing a significant advancement in firefighter safety.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"5 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538350","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 demonstrate a highly stretchable organic optoelectronic synaptic transistor (s-OOST) with a transconductance up to 86 mS that can simultaneously accept modulation of electrical pulses and multi-wavelength light signals (from ultraviolet to near-infrared). The s-OOST achieved highly reliable synaptic plasticity for brain-inspired computation and retina-inspired perception even under 50% tensile strain. Furthermore, the devices exibited vision-adaptive near-infrared sensing ability that was verified by single-pixel scanning imaging. Finally, the multi-wavelength (365 nm–1050 nm) optical synaptic properties were investigated under the applications of imaging memory, polychromatic optical communication and information security (coded by wavelength). This research advances the capabilities of the stretchable integrated systems with vision-adaptive sensing characteristic and computing-in-memory ability.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"49 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528244","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}

Ideally, electronic skin (e-skin) integrates identity information and tactile sensing, but this remains challenging. Research on encryption and tactile sensing rarely overlaps. Here, we report using magnetization structures and combinations of magnetic materials to achieve two types of functions: 6n × n invisible secure encryption is achieved through a n × n dipole magnetic array, and multipole magnets are used to achieve decoupling of pressure at various positions and sliding in different directions. The sliding distance ranges from 0 to 2.5 mm, with speeds between 5 and 25 mm/s. This study is based on flexible magnetic films, which have the potential to be used in wearable devices. The magnetic ring and signal detection modules verify the prospects of this fundamental principle in human-computer interaction (HCI) and demonstrate its applications in user identity recognition and tactile interaction.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"51 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143517993","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 challenge lies in replicating these fractal surfaces at the microscale in a way that is scalable, freestanding, and integrable with various materials. In this study, we present a novel method for the biomimetic microfabrication of leaf-skeleton-based fractal surfaces. We utilized a modified electrospinning method, replacing the fiber collector with a metalized biotic collector to replicate the microstructures. The biomimetic microfractals demonstrated ~90% replication accuracy, >80% transparency, good stretchability, and breathability, and were freestanding. The method is versatile, allowing for the use of a wide range of polymers in biomimetic microfabrication. For application in flexible electronics, biomimetic conductive fractal patterns (BCFP) were fabricated by immobilizing Ag Nanowires (AgNW) using a simple spray-based method. The BCFP exhibited high conductivity with sheet resistances <20 Ω sq–1 while maintaining good transparencies. The BCFP adheres conformally to human skin, acting as an electronic skin (e-skin). To demonstrate the application, the BCFP was used to fabricate a tactile pressure sensor. In addition to their excellent transparency at low sheet resistances, stretchability, moisture resistance, and tight conformal bonding with the target surface, the BCFP also allows the evaporation of perspiration, making them suitable for long-term use as epidermal sensors. The application of BCFP in advanced bionic skin was demonstrated through gesture monitoring experiments.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"115 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418363","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}
