The elements of wearable bioelectronics should feature elastoplasticity (i.e., tough and stretchable characteristics) to surmount the volumetric stress exerted by daily motions. To this end, the canonical amino acid is tailored as an intrinsic crosslinker through the silk fibroin electrode to dissipate the transferred loads. Specifically, the phenolic building block is designed to (1) expose along the amorphous strands and (2) form the stress dissipative network. Raman marker supports in situ visualization of crosslink degree. Hence, the weavable biopolymer electrode boasts (1) super-elastoplasticity (700 MJ m-3 toughness, 350% stretchability) enduring the active workouts and (2) reliable electrical responses under the motion-induced strains (i.e., < 20% deviations of resistance). Besides, the model smart sportswear embarks the analogous roles of a personal trainer supporting the workout efficiency, namely, suppression of muscular fatigues or injuries during workouts. |
