Piezoelectric ceramic formula adaptive to road vibration energy harvesting technology, preparation method and application thereof

The invention relates to a piezoelectric ceramic formula adaptive to a road energy harvesting technology, a preparation method and application thereof, the piezoelectric ceramic formula is mainly composed of a main component and additional components, the main component is PbxSryBa1-x-y (Zr0. 54Ti0. 46) z (Sb0. 58Nb0. 42) 1-zO3, 0.7 < = x < = 0.75, 0.02 < = y < = 0.06, 0.95 < = z < = 0.98, the additional components are CaCO3 and CdCO3 accounting for 0.2 wt% of the mass of the main component, and the sum of the components is 100%. According to the chemical formula of PbxSryBa1-x-y (Zr0. 54Ti0. 46) z (Sb0. 58Nb0. 42) 1-zO3, the steps of burdening, pre-sintering, secondary ball milling, forming, plastic removal, sintering, slicing, silver firing, polarization and the like are carried out to prepare a ceramic chip, the ceramic chip is made into a piezoelectric transducer to be applied to a road, the optimal power generation performance is obtained under the condition that the road use condition is met, and the se
