Abstract Leveraging the fluidity and excellent conductivity of liquid metal (gallium‐indium alloy), (LM) can be utilized to manufacture flexible stretchable electronic products for applications in soft robotics, wearable devices, human–machine interaction. However, high surface tension low adhesion LM hinder its patterning high‐resolution fabrication electronics. Here a recyclable LM‐silicon dioxide (LMS) ink is proposed. Under stirring, silicon (SiO 2 ) particles are encapsulated by oxide layer LM, consuming layer. Meanwhile, gallium reacts with oxygen from air form new layer, enhancing substrate while maintaining conductivity. The in‐situ printing LMS verified on various materials (e.g., paper, polymer, glass) resolution up 165 µm an exceptional ≈6.53 × 10 6 S m −1 . printed patterns erased anhydrous ethanol solution, allowing recovered reused multiple writing cycles. general method direct circuits fabricate sensors devices

Abstract Electronic devices are ubiquitous in modern society, yet their poor recycling rates contribute to substantial economic losses and worsening environmental impacts from electronic waste (E‐waste) disposal. Here, recyclable healable electronics reported through a vitrimer‐liquid metal (LM) microdroplet composite. These electrically conductive, plastic‐like composites display mechanical qualities of rigid thermosets recyclability dynamic covalent polymer network. The composite exhibits high glass transition temperature, good solvent resistance, electrical conductivity, recyclability. vitrimer synthesis proceeds without the need for catalyst or curing which enables facile fabrication materials. as‐synthesized fast relaxation time with reconfigurability shape memory. conductive conductivity LM volume loading as low 5 vol.%.

Abstract As the body's largest organ, skin is an integrated multisensory system with self‐healing ability and helps stabilize body temperature. It herein, inspired by natural skin, a wearable patch made from porous polydimethylsiloxane (PDMS) skeleton, poly(vinyl alcohol) (PVA) hydrogel, silicon oxide (SiO 2 ) particles, offers combination of properties, along hybrid radiative evaporative cooling mechanisms, designed for electromyographic (EMG) signal detection human‐machine interaction. The has both high mid‐infrared (MIR) emittance (96%) visible to near‐infrared (visNIR) reflectance (80%), coupled efficient water evaporation PVA resulting in power 180 W m −2 . obtains temperature drop ≈7.7 °C using this under solar intensity ≈700 Furthermore, demonstrates ultrafast recovery electrical conductivity (1 s) efficiency (≈71%) fracture strain. Thus, can detect high‐quality EMG signals provide effects capabilities that enhance comfortability durability. These features make advanced solution developing next‐generation patches meet rigorous demands durable control various applications.

Abstract Flexible and wearable electronics have gained extensive attention in health monitoring, electronic skin, sensors due to their flexibility, portability, sensitivity, biocompatibility. Liquid metal (LM) is an optimum conductive material for soft devices because of its high conductivity fluidity at room temperature. Nevertheless, LM with stable dimension a formidable challenge relatively surface tension mass density. In this study, we introduce wet spinning approach that utilises sodium alginate as the exterior phase interior phase. Calcium lactate used solidify alginate, thereby producing liquid microfibers (LMMs). The LMMs can be modified by adjusting flow rate two-phase materials. encapsulated microcapsule serve healing switch suitable use flexible devices. Initially, (LMSS) has resistance value. Once specific amount pressure applied, value drops considerably resulting switch’s activation. And coated dissolve trisodium citrate solution, so reshaped under mixed each other. It achieves LMSS’s reusability recycling.

Liquid metals (LMs) illustrate a fantastic future. Thus, great endeavors are made to earn comprehensive understanding of this fluid and carve it into niche. Herein, by revisiting the combination Ga-based LMs aluminum (Al), new phenomenon, namely disintegration LM films on encountering water, is identified. Deviating from previous investigations where generally took form bulk puddles, LM-Al slurry spread as thin here. In case, Al debris embedded in matrix hydrolyzes therefore can exert disjoining pressure strong enough split film countless tiny droplets. Based mechanism, transient circuits independent substrate decomposition realized. Furthermore, taking advantage portfolio strategy pure slurry, novel concepts flood warning information storage encryption demonstrated. Integrating these functions all one demonstrates versatility engendered corrosion, which provides scientific insight ephemeral art makes Ga─Al more illuminating.
