With the gradual increase of wearable devices in the market，more and more attention is focused on stretchable sensors. Stretchable strain sensors have the advantages of large stretch strain range，high sensitivity，fast response speed，high stability，and good durability. Therefore，stretchable strain sensors have enormous application potential in fields such as medical health，motion detection，intelligent robots，human-machine interaction，and virtual reality entertainment technology. This article summarizes the theoretical knowledge and research progress in the field of stretchable strain sensors. Firstly，we introduce two ways to make strain sensors stretchable，and then classify them according to their sensing mechanisms. Next，the new materials used for making stretchable strain sensors and the relevant performance parameters of strain sensors are introduced，and the relevant progress of stretchable strain sensors in recent years is summarized. Finally，based on the current development and application of stretchable strain sensors，the existing problems and future research directions of stretchable strain sensors are summarized.
