The invention provides a method for adjusting the energy harvesting performance of a piezoelectric semiconductor fiber through a variable cross-section, and the method comprises the steps: enabling one end of the piezoelectric semiconductor fiber to be fixedly supported, enabling the other end of the piezoelectric semiconductor fiber to be subjected to a shearing force perpendicular to the piezoelectric semiconductor fiber, and forming a cantilever beam structure; the piezoelectric semiconductor fiber satisfies a piezoelectric semiconductor aesthetic theory motion equation. Through the structural design of the variable cross section, the potential distribution condition in the piezoelectric semiconductor fiber is changed, the efficiency of collecting the potential energy is improved, and the capturing performance of the potential energy is improved. 本发明提供了一种通过变截面调节压电半导体纤维俘能性能的方法，包括：所述压电半导体纤维的一端受到固定支撑，另一端受到垂直于所述压电半导体纤维的剪切力，以构成悬臂梁结构；所述压电半导体纤维满足压电半导体唯象理论运动方程。本发明通过变截面的结构设计改变压电半导体纤维内部电势分布情况，提升收集电势能效率，提高电势能的俘获性能。
