Abstract Electronic skins (E‐skins) capable of biomechanical/bioelectrical signal acquisition are intensively pursued for human‐centered healthcare daily life. For practical use, it is highly desired, yet challenging, to mass‐produce E‐skins that soft and breathable wearing comfort, skin‐adhesive robust acquisition, multi‐signal sensing enhanced data. Herein, a scalable fabrication strategy bioinspired E‐skin (SPRABE‐skin) with multi‐layered architecture reported integrates skin‐like softness, self‐protection, self‐adhesion, breathability, bimodal in single patch. The fibrous thermoplastic polyurethane (TPU) scaffold endows the SPRABE‐skin tissue‐like softness (Young's modulus 3.36 MPa) stretchability, good permeability water vapor, self‐protection against adverse loading events. A strain layer composed MXene‐carbon nanotubes@TPU (MXene‐CNT@TPU) composition exhibits ultra‐high sensitivity wide range (gauge factor at 485% reaches 63 494). An electrode made MXene‐waterborne (MXene‐WPU) provides adhesive electrode‐skin interface, which enables biopotentials, such as electrocardiograph (ECG), electromyograph (EMG), electroencephalo‐graph (EEG), improved fidelity even under various dynamic interferences. Finally, based system demonstrated realizes wireless, long‐duration, monitoring ECG running activities.

Abstract Flexible strain sensors with high sensitivity and mechanical robustness are highly desirable for their accurate long‐term reliable service in wearable human‐machine interfaces. However, the current application of flexible has to face a trade‐off between robustness. The most representative examples micro/nano crack‐based serpentine meander‐based sensors. former one typically shows but limited robustness, while latter is on contrary. Herein, ultra‐robust sensitive developed by crack‐like pathway customization ingenious modulation low/high‐resistance regions meander structure. show cyclic stability (10 000 cycles), strong tolerance harsh environments, gauge factor (>1000) comparable that sensor, fast response time (<58 ms). Finally, integrated into sign language translation system, which wireless, low‐cost, lightweight. Recognition rates over 98% demonstrated 21 languages assistance machine learning. This system facilitates achieving barrier‐free communication signers nonsigners offers broad prospects gesture interaction.

Abstract With the development of science and technology, scale industrial production continues to grow, types quantities gas raw materials used in produced during process are also constantly increasing. These gases include flammable explosive gases, even contain toxic gases. Therefore, it is very important necessary for sensors detect monitor these quickly accurately. In recent years, a new two-dimensional material called MXene has attracted widespread attention various applications. Their abundant surface functional groups sites, excellent current conductivity, tunable chemistry, outstanding stability make them promising sensor Since birth materials, researchers have utilized efficient convenient solution etching preparation, high flexibility, easily functionalize with other prepare composites sensing. This opened chapter high-performance sensing provided approach advanced research. However, previous reviews on MXene-based composite only focused performance sensing, without systematically explaining mechanisms generated by different as well summarizing predicting advantages disadvantages materials. article latest progress application Firstly, brief summary was given commonly methods preparing device structures, followed an introduction key attributes related performance. focuses such MXene/graphene, MXene/Metal oxide, MXene/Transition metal sulfides (TMDs), MXene/Metal–organic framework (MOF), MXene/Polymer. It summarizes discusses possible Finally, future directions inroads MXenes-based presented discussed.

Flexible pressure sensors play a significant role in wearable devices and electronic skin. Iontronic with high sensitivity, wide measurement range, resolution can meet requirements. Based on the deformation characteristics of alveoli to improve compressibility, ability arch disperse vertical into horizontal thrust increase contact area, graded hollow ball (GHBA) microstructure is proposed, greatly improving sensitivity. The fabrication GHBA ingeniously employs double-sided structure. One side uses mold casting create convex structures, while other utilizes evaporation moisture during curing process form concave structures. At same time, novel side-by-side package structure ensuring flexible substrate maximally transferred microstructure. Within range 0.2 Pa-300 kPa, iontronic sensor achieves maximum sensitivity 10 420.8 kPa
