Waistband with piezoelectric energy collecting function

The invention discloses a waistband with a piezoelectric energy collecting function. Based on a traditional waistband, a piezoelectric element is arranged on the inner wall or the outer wall or in an interlayer of a waistband body in the length direction of the waistband body. When the waistband is in a use state, the abdomen constantly contracts and expands in the breathing process of the human body, force is shown as changing tension and pressure when transmitted to the waistband, and changing charges can be generated on the surface of a piezoelectric material arranged on the waistband body due to the borne changing tension or pressure action according to the direct piezoelectric effect. When an electrode lead of the piezoelectric element is connected with a corresponding piezoelectric energy collecting circuit, mechanical energy generated by the breathing abdominal movement of the human body can be converted into electric energy, and the electric energy can be collected and stored for supplying power to ot
