Flexible electronic circuits are critical in biomedical devices, human–machine interfaces, and wearable sensing systems, which further require flexible conductive materials with high conductivity, stretchability, electrical stability. Liquid metal (LM) has attracted much attention due to its unique metallic conductivity room-temperature fluidic properties. However, LM's surface tension properties increase the difficulty of patterning processing. Here, we report a scalable simple fabrication method based on femtosecond laser ablation for facile patterned LM Cu composite electrodes (LM@Cu) substrates. The LM@Cu electrodes, fabricated utilizing exceptional micro–nanoprocessing precision three-dimensional capabilities lasers, exhibit resolution (approximately 5 μm), superior (4.08 × 104 S/cm), enhanced In addition planar circuits, successfully 3D-patterned electrode PDMS hemispheres. presence ultrathin copper foils significantly improves wettability substrate, occurrence alloying reactions between circumvents challenges posed by pattern fabrication. We investigated electromechanical under twisting, bending, stretching detail. addition, serve as an interface rigid devices When suffering external damage, remain working after brush coating excellent fluidity LM. To explore this approach's potential, demonstrate various applications electronics, including stretchable luminous wristbands, strain sensors, "visible" thermotherapy panels relieving aching joints.

Spider Silk‐Inspired Conductive Hydrogels for Enhanced Toughness and Environmental Resilience via Dense Hierarchical Structuring

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Фев. 4, 2025

Abstract Conductive hydrogels, known for their biocompatibility and responsiveness to external stimuli, hold promise biomedical applications like wearable sensors, soft robotics, implantable electronics. However, broader use is often constrained by limited toughness environmental resilience, particularly under mechanical stress or extreme conditions. Inspired the hierarchical structures of natural materials spider silk, a strategy developed enhance both tolerance in conductive hydrogels. By leveraging multiscale dynamics including pores, crystallization, intermolecular interactions, dense structure created that significantly improves toughness, reaching ≈90 MJ m⁻ 3 . This hydrogel withstands temperatures from −150 70 °C, pressure 12 psi, one‐month storage ambient conditions, while maintaining lightweight profile 0.25 g cm⁻ Additionally, its tunable rheological properties allow high‐resolution printing desired shapes down 220 µm, capable supporting loads exceeding 164 kg 2 study offers versatile framework designing durable various applications.

Rapidly self-healing electronic skin for machine learning–assisted physiological and movement evaluation

Science Advances, Год журнала: 2025, Номер 11(7)

Опубликована: Фев. 12, 2025

Emerging electronic skins (E-Skins) offer continuous, real-time electrophysiological monitoring. However, daily mechanical scratches compromise their functionality, underscoring urgent need for self-healing E-Skins resistant to damage. Current materials have slow recovery times, impeding reliable signal measurement. The inability heal within 1 minute is a major barrier commercialization. A composition achieving 80% has not yet been reported. Here, we present rapidly E-Skin tailored monitoring of physical and physiological bioinformation. recovers more than its functionality 10 seconds after damage, without the external stimuli. It consistently maintains biometric assessment, even in extreme environments such as underwater or at various temperatures. Demonstrating potential efficient health achieves an accuracy exceeding 95%, excelling wearable muscle strength analytics on-site AI-driven fatigue identification. This study accelerates advancement through rapid capabilities.

Electrochromic (EC) technology has become one of the smart technologies with most potential for development and application at this stage. Based on electrochromic devices (ECDs), shown extraordinary in fields windows, display devices, sensing systems. With optimization iteration various core components ECDs, electrolyte layer, a key component, evolved from its initial liquid state to quasi-solid solid state. As driven by increasing demands, trend indicates that all-solid-state, transparent electrolytes will likely future form layer. Recently, ionic (IL)-based field electrochromism attracted lot attention due their ability bring outstanding EC cycling stability, thermal wider operating voltage range they are regarded as new generation materials application. Although compared conventional electrolytes, IL-based have characteristics high price, viscosity, low conductivity, still considered promising applications. However, so far, there been lack comprehensive analysis reports “Research progress liquid-based devices” within field. In article, research ECDs be summarized three perspectives: liquid, quasi-solid, The directions discussed.
