In order to further understand the current research progress of piezoelectric materials in intelligent heating shoes, the application advantages of piezoelectric intelligent heating shoes are analyzed, and the existing research results are summarized. It is pointed out that due to the inherent limitations of piezoelectric materials, low piezoelectric power generation and difficulty in storing piezoelectric energy s are the technical bottlenecks that limit the development and application of piezoelectric intelligent heating shoes. Currently, piezoelectric heating shoes generally suffer from poor thermal and wet comfort, low miniaturization of electronic components, low functional integration and bulky shoe body, which affect wearing comfort and convenience. Suggestions can be addressed from the following five aspects: developing and upgrading a new generation of piezoelectric materials, designing new piezoelectric structures using the piezoelectric effect of piezoelectric materials, optimizing the design of new energy collection circuits, and improving the integration and intelligence of functions through the use of antibacterial, odor proof, breathable, and comfortable new materials.
