Abstract Triboelectric nanogenerators (TENGs) are an emerging energy‐harvesting technology capable of converting mechanical energy into electrical energy. However, triboelectric layers, crucial components TENGs, susceptible to and structural damage in harsh environments, thereby compromising the device's output performance limiting its applicability. Therefore, developing layers with excellent strength environmental stability poses a challenge. Inspired by intricate multiple cross‐linking networks present myofibrillar proteins, strategy is proposed prepare conductive special rubbers outstanding (13.5 MPa), stability, conductivity (0.86 S m −1 ) using “grafting–hydrogenation–cross‐linking–filling” process. The considerably enhanced rubber's 100 times (0.3–30.3 MPa). Subsequently, these employed as accordion‐structured which demonstrated exceptional open‐circuit voltage 723 V power density up 3.25 W −2 . TENGs can operate stably wide range environments. This study provides viable for designing functioning contributing sustainable solutions.
