In this article, the captions for Figures 5 and 6 were inadvertently omitted. The correct captions are given below. Fig. 5 Pre-formed tissue-adhesive hydrogel interfaces for muscle repair. (a) SSGAE: sticky, strain-gradient artificial epineurium with an instant wet-adhesive layer and two hydrophobic elastomer layers that redistribute strain, enabling sutureless repair and drug-reservoir functionality from rodents to non-human primates. (b) TA-SA-PNI: laser-patterned Cu/Au serpentine embedded in a self-healing polymer with a phenylboronic-acid alginate primer, providing stiffness-adaptive, suture-free, stable bidirectional interfacing on sciatic nerve under large strain. (c) CA-HE film electroceutical: Janus alginate (adhesive AlBA layered with elastic AlMA) supporting soft PEDOT:PSS electrodes; the thin, gradient cuff self-locks on small-diameter nerves and lowers stimulation thresholds. (d) Adhesive nerve bandage (ANB/ACNB): polypyrrole-doped hydrogel fibers wrap and adhere to wet sciatic nerve without sutures, preserving conformal contact during motion. Fig. 6 Schematic of an injectable, wet-adhesive conductive hydrogel delivered into a muscle defect to provide immediate low-impedance coupling (lightning icon) and conformal sealing. The outer ring summarizes the design logic: (i) address mechanical mismatch and durable wet adhesion on contracting tissue; (ii) enable minimally invasive deployment with on-demand top-ups of cells/drugs; (iii) support closed-loop therapy (stimulation/recording) for force recovery; and (iv) incorporate bioactive release (growth factors/anti-oxidants) to steer regeneration. Co-designed adhesion with conduction via phenolic/quinone, boronate or dynamic-imine bonding integrated with soft-electronic phases (e.g., conducting polymers, MXenes, carbons) maintains contact through strain and motion, limiting impedance drift. Looking forward, temporal adaptivity is emphasized: high initial fixation to prevent washout, followed by controlled relaxation as tissue heals, yielding suture-free interfaces that seal, sense, and stimulate from placement through recovery.
