The pursuit of constructing humanoid robots to replicate the anatomical structures and capabilities human beings has been a long-standing significant undertaking especially garnered tremendous attention in recent years. However, despite progress made over decades, have predominantly confined those rigid metallic structures, which however starkly contrast with inherent flexibility observed biological systems. To better innovate this area, present work systematically explores value potential liquid metals their derivatives facilitating crucial transition towards soft robots. Through comprehensive interpretation bionics, an overview metals' multifaceted roles as essential components advanced robots-functioning actuators, sensors, power sources, logical devices, circuit systems, even transformable skeletal structures-is presented. It is conceived that integration these flexible facilitated by unique properties metals, can create unexpected versatile functionalities behaviors fulfill needs. Finally, revolution envisioned, transitioning from frameworks hybrid soft-rigid resembling tissues. This study expected provide fundamental guidance for coming research, thereby advancing area.

Abstract Epidermal electronics has garnered significant research attention due to its promising applications in wearable human‐machine interfaces and intelligent healthcare sensing. However, their widespread use faces challenges complex manufacturing processes, high material costs, inadaptability different skin surfaces, inadequate reusability. Herein, inspired by the biological reshapability environmental adaptability of amoeba, an ultra‐deformable (≈2600% strain), bioadhesive (adhesive strength ≈3 kPa), strong self‐healing (fastest recovery time ≈1s, maximum wound distance ≈5 mm), electromechanical‐durable electronic slime (E‐slime) is proposed, which can instantaneously form on‐skin situ detect body motion physiological signals. E‐slime demonstrates desired sensing performance with sensitivity (gauge factor 2.95), wide range (up 400% low detection limit (≈1% seamlessly adhere be easily reused multiple times (≈100 cycles usage). also enables on‐the‐fly deployment monitoring tasks at various locations, showcasing versatility reliability for recognition personal health monitoring. This study holds potential next‐generation green electronics, devices, interfaces, ultimately helping ensure healthy lives promote well‐being.

Abstract Epoxy resin (EP), as a material with excellent insulation performance, has been widely applied in fields such electronics, coatings, ships etc. However, epoxy resins generally have poor thermal conductivity, which limits their application the field of new generation electronic packaging. To address key issues mentioned above, BN@Fe 3 O 4 particles positive out‐of‐plane conductivity were successfully prepared this study, having core‐shell structure rough surfaces well. As conductive powder, disadvantage hexagonal boron nitride being easily agglomerated improved. By applying an external magnetic field, three‐dimensional conduction pathways constructed matrix. The physical and chemical properties powder its composite materials analysed tested. experiment indicates that had prepared. When filling amount reached 27.5 vol%, was 1.758 W m −1 K , 982.12% pure EP. At point, mechanical behaviour performance EP can be effectively guaranteed at same order magnitude performance.
