The invention discloses a preparation method of a piezoelectric film sensor for preventing lung diseases, which comprises the following steps: obtaining a mixed solution based on lead zirconium titanate and tetrahydrofuran; neutralizing polyurethane based on the mixed solution to obtain a preparation solvent; manufacturing an electrode based on the preparation solvent; and manufacturing the piezoelectric film sensor based on the electrode. By improving the ratio of PZT to PU and THF, the sensitivity and resolution of the product are improved, so that the aim of detecting early-stage lung diseases is fulfilled. In addition, compared with other products, the manufacturing process is simpler, the manufacturing cost is lower, and popularization and application of the invention are more facilitated. Compared with the prior art, the flexible piezoelectric film sensor is excellent in piezoelectric property, flexibility, chemical stability, reliability and the like, and has a wide application prospect. 本发明公开了一种用于预防肺部
