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}

However, achieving a crystal environment to suppress the non-radiative transition of triplet excitons poses a challenge in constructing stretchable afterglow materials. Herein, we utilize an in situ supersaturated crystallization strategy to form afterglow microcrystals within a hydrogel matrix. This approach enables afterglow emission with a lifetime of 695 ms while maintaining high stretchability with tensile stress surpassing 398 kPa, extensibility over 400% and a high water content of 65.21%. Moreover, the universal supersaturated crystallization strategy allows for conferring tunable afterglow performance. Successful demonstrations in hydrogel 3D printing and anti-counterfeiting purposes showcase the potential for advanced applications of 3D printable afterglow hydrogels. This investigation provides guidelines for generally designing efficient afterglow hydrogels and addresses the inherent contradiction between flexibility and rigid in stretchable afterglow materials.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"75 1 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071546","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}

Currently, the standard silver/silver chloride (Ag/AgCl) gel electrodes may cause skin irritation when worn for a long time. Repeating the use of electrodes on different individuals can lead to the risk of cross-infection. Here, we propose a smart electronic tape (SET) to acquire biopotentials, in the form of a dry single-sided tape made from a combination of an ultra-stretchable conductive pattern on substrates with different functions. The high stability and durability of the patterned conductors provide accurate and timely acquisition of biopotentials, such as electrocardiograph (ECG) and electromyography (EMG). The strong adhesive behavior of the tape as well as the low-cost manufacturing process allow convenient and long-term wearing in a disposable manner. We anticipate the SET will pioneer next-gen wearable electronics for applications like disease prevention, health monitoring, and human–computer interaction.","PeriodicalId":48528,"journal":{"name":"npj Flexible Electronics","volume":"60 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056661","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}
