Developing materials with structural flexibility that permits self‐repair in response to external disturbances remains challenging. Spider silk, which combines an exceptional blend of strength and pliability in nature, serves as an ideal dynamic model for adaptive performance design. In this work, a novel self‐healing material is generated using spider silk. Dragline silk from spider Nephila pilipes is demonstrated with extraordinary in situ self‐repair property through a constructed thin film format, surpassing that of two other silks from spider Cyrtophora moluccensis and silkworm Bombyx mori. Subsequently, R2, a key spidroin associated with self‐healing, is biosynthesized, with validated cohesiveness. R2 is further programmed with tunable healability (permanent and reversible) and conductivity (graphene doping; R2G) for electronics applications. In the first demonstration, film strips from R2 and R2G are woven manually into multidimensional (1D‐3D) conductive fabrics for creating repairable logic gate circuits. In the second example, a reversibly‐healable R2/R2G strip is fabricated as a re‐configurable wearable ring probe to fit fingertips of varying widths while retaining its detecting capabilities. Such a prototype displays a unique conformable wearable technology. Last, the remarkable finding of self‐healing in spider silk can offer a new material paradigm for developing future adaptive biomaterials with tailored performance and environmental sustainability.

“…[14][15][16][17][18] To develop a more efficient adhesion system, it is important to induce the interdiffusion of polymer chains between two cured rubber samples during an adhesion process, such as heat-pressing, followed by interlinkage between the two rubber samples after cooling. Hence, the introduction of reversible linkages, 1,[19][20][21][22] such as hydrogen bonds, [23][24][25][26] ionic interactions, [27][28][29][30][31][32][33] host-guest interactions, 34,35 dynamic covalent bonds [36][37][38][39][40][41][42][43][44][45] and metal-ligand coordination bonds, 25,[46][47][48][49][50][51][52][53][54][55] given that introducing cross-linking bonds into cured rubber is a potential strategy to achieve direct adhesion between cross-linked rubbers, as reversible linkages often show a temperature dependence that is different from that of conventional covalent bonds, which results in good malleability at high temp...…”
