In the era of Internet-of-things, many things can stay connected; however, biological systems, including those necessary for human health, remain unable to connected global Internet due lack soft conformal biosensors. The fundamental challenge lies in fact that electronics and biology are distinct incompatible, as they based on different materials via functioning principles. particular, body is curvilinear, yet typically rigid planar. Recent advances design have generated tremendous opportunities wearable bioelectronics, which may bridge gap, enabling ultimate dream healthcare anyone, anytime, anywhere. We begin with a review historical development healthcare, indicating significant trend healthcare. This followed by focal point discussion about new design, particularly low-dimensional nanomaterials. summarize material types their attributes designing bioelectronic sensors; we also cover synthesis fabrication methods, top-down, bottom-up, combined approaches. Next, discuss energy challenges progress made date. addition front-end devices, describe back-end machine learning algorithms, artificial intelligence, telecommunication, software. Afterward, integration systems been applied various testbeds real-world settings, laboratories preclinical clinical environments. Finally, narrate remaining conjunction our perspectives.

Continuous monitoring of blood pressure (BP) and multiparametric analysis cardiac functions are crucial for the early diagnosis therapy cardiovascular diseases. However, existing approaches often suffer from bulky intrusive apparatus, cumbersome testing procedures, challenging data processing, hampering their applications in continuous monitoring. Here, a heterogeneously hierarchical piezoelectric composite is introduced wearable BP function monitoring, overcoming rigidity ceramic insensitivity polymer. By optimizing structure components composite, developed sensor delivers impressive performances, ensuring accurate at Grade A level. Furthermore, hemodynamic parameters extracted detected signals, such as local pulse wave velocity, output, stroke volume, all which alignment with clinical results. Finally, all-day tracking validates reliability stability sensor, highlighting its potential personalized healthcare systems, particularly timely intervention disease.

High-performance flexible piezoresistive sensors are becoming increasingly essential in various novel applications such as health monitoring, soft robotics, and human–computer interaction. The evolution of the interfacial contact morphology determines sensing properties devices. introduction microstructures enriches effectively boosts sensitivity; however, limited compressibility conventional leads to rapid saturation sensitivity low-pressure range, which hinders their application. Herein, we present a sensor featuring two-stage micropyramid array structure, enhances while widening range. Owing synergistic enhancement effect resulting from sequential micropyramids heights, devices demonstrate remarkable performance, including boosting (30.8 kPa–1) over wide range (up 200 kPa), fast response/recovery time (75/50 ms), an ultralong durability 15,000 loading–unloading cycles. As proof concept, is applied detect human physiological motion signals, further demonstrating real-time spatial pressure distribution system game control system, showing great potential for monitoring

Abstract Developing green and efficient preparation strategies is a persistent pursuit in the field of 2D transition metal nitrides and/or carbides (MXenes). Traditional etching methods, such as HF‐based or high‐temperature Lewis‐acid‐molten‐salt route, require harsher conditions exhibit lower efficiency with limited scalability, severely constraining their commercial production practical application. Here, an ultrafast low‐temperature molten salt (LTMS) method presented for large‐scale synthesis diverse MXenes within minutes by employing NH 4 HF 2 etchant. The increased thermal motion improved diffusion molecules significantly expedite process MAX phases, thus achieving Ti 3 C T x MXene just 5 minutes. universality LTMS renders it valuable approach rapid various MXenes, including V , Nb Mo TiC CT . easy to scale up can yield more than 100 g single reaction. obtained LTMS‐MXene exhibits excellent electrochemical performance supercapacitors, evidently proving effectiveness method. This work provides ultrafast, universal, scalable MXenes.
