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.

Abstract Pure room‐temperature phosphorescence (pRTP) promises great advantages in both exciton utilization and lifetime manipulation over existing organic luminophores for a variety of emerging applications, but the low brightness, efficiency, color purity constrain afterglow luminescence significantly. Here, promising approach to design highly bright, efficient, narrowband pRTP with long‐lifetime hyperafterglow is proposed by isolating conjugated energy donor circularly polarized (CP) acceptor multi‐resonance effect into rigid host. It shown that aggregation chiral P‐containing binaphthyl promotes generation CP‐pRTP high brightness up ≈50 cd m −2 , while simultaneous transfer chirality afford multi‐color photoluminescence efficiency ≈90%, full‐width at half maxima 31–39 nm, 120–770 ms, luminescent dissymmetry ≈10 −3 . Also, excellent stability capable resisting quenching effects oxygen, solvents, aqueous solutions strong acids bases are observed. With these advantages, applications information encryption, grayscale imaging, 3D high‐resolution models realized, promoting significantly fundamental understandings on modulation construction high‐performance materials advanced photophysical properties applications.
