Abstract Electronic waste is a growing threat to the global environment and human health, raising particular concerns. Triboelectric devices synthesized from sustainable degradable materials are promising electronic alternative, but mechanical mismatch at interface between polymer substrate electrodes remains unresolved in practical applications. This study uses sulfhydryl silanization reaction chemical selectivity site specificity of thiol–disulfide exchange dynamic covalent chemistry prepare tough monolithic‐integrated triboelectric bioplastic. The stress dissipated by bond adaptation interaction, which makes dielectric layer conductive have good adhesion effect (220.55 kPa). interfacial interlocking with gives bioplastic excellent tensile strength (87.4 MPa) fracture toughness (33.3 MJ m −3 ). Even when subjected tension force 10 000 times its weight, it still maintains stable output no visible cracks. provides new insights into design reliable environmentally friendly self‐powered devices, significant for development flexible wearable electronics.
