The incorporation of waterborne polyurethane (WPU) into bacterial cellulose (BC) fibers significantly improved the tensile strength resulting WPU/BC composite film, achieving an enhancement 19.4 times. formation hydrogen bonds between WPU and BC effectively eliminates cavities within matrix, significant plasticization toughening. Compared with pure film (WPU/BC-0), elastic modulus WPU/BC-5 is reduced by 97.5%, surface hardness decreased 96.9%. When integrated a flexible EGaIn electrode, wearable demonstrated exceptional potential in electronics, reliably enabling point-of-care detection human electrocardiograph (ECG) signals. This WPU-regulated approach provides promising alternative for fabricating durable substrates suitable device applications.
