Mechatronics has become an inevitable trend in the development of the industry, manufacturing industry in the rapid development of today has also driven the innovation of technology. In the development process of mechatronics, flexible sensors stand out, flexible sensors have the characteristics of flexibility, and a wider range of applications, which is the frontier direction of contemporary electromechanical development. Mechanical and electronic engineering is for the traditional engineering disciplines, the teaching process of students to accept concepts and other content ability is poor, lack of interest, the need for new solutions to solve problems. And by using flexible sensors in exemplary teaching, electromechanical knowledge can be taught more effectively, which can enhance students' vision, learning ability, indepe, dance, and innovation. In this paper, we outline the principles of flexible sensors, and sensors in electromechanical engineering, the advantages and disadvantages of each type of flsensorsensors, and their broad prospects for electromechanical teaching applications.
