The development of piezoelectric biomaterials with the capability to produce electrical signals and scavenge reactive oxygen species (ROS) is a novel strategy for stimulating osteoblast responses promoting bone regeneration. Herein, tungsten (W), iridium (Ir), ruthenium (Ru) codoped bismuth molybdate (4(W/Ru/Ir)-BMO) nanosheets improved piezoelectricity enzyme-like (CAT-like SOD-like) activities were constructed by using hydrothermal method. A composite hydrogel oxidized sodium alginate/gelatin (OSA/GEL) 4(W/Ru/Ir)-BMO (OSA/GEL/4-B) was also prepared. Due presence 4(W/Ru/Ir)-BMO, OSA/GEL/4-B exhibited not only but activities. Under ultrasound (US), generated that significantly promoted proliferation osteogenic differentiation marrow stromal cells. Furthermore, effect CAT-like (production oxygen) SOD-like (scavenger ROS) attributed codoping W, Ir, Ru ions, which resulted in lattice distortion enhanced crystal asymmetry, produced regulating microenvironment. Moreover, improvement field triggered US accelerated electron transfer alleviating cellular oxidative stress provided an antioxidant microenvironment responses. This may provide pathway
