Summary:The invention provides a flexible ultrasonic device for ultrasonic treatment and a preparation method of the flexible ultrasonic device. The flexible ultrasonic device comprises an excitation circuit,a target flexible substrate, an acoustic matching layer and a plurality of piezoelectric devices with different inherent frequencies, wherein the excitation circuit is electrically connected with theplurality of piezoelectric devices to enable the plurality of piezoelectric devices to emit ultrasonic waves with different frequencies; the plurality of piezoelectric devices are combined with the target flexible substrate; the target flexible substrate is used for being attached to the surface of a human body; and the sound matching layer is combined with the target flexible substrate to package the plurality of piezoelectric devices. The flexible ultrasonic device mechanically stimulates a wound, which can reverse aged fibroblasts, thereby effectively promoting healing of a chronic wound.Moreover, the flexible ultr
