Abstract: The self-research and self-production of experimental equipment plays an important role in cultivating the innovation consciousness and improving the practical ability of college students. Around the test of conductive polymer flexible devices, the digital multimeter is combined with universal testing machine. According to the characteristics of materials and test requirements, the students adjust the matching of two devices by hand under the guidance of the tutor, and finally obtain the equipment to test conductive polymer flexible devices. Through the self-developed self-made testing and evaluation system, students can fully exercise in the process of participating in the research of cutting-edge scientific research results and cultivate their comprehensive innovation ability. At the same time, through the research and development of self-made equipment, the school can better research and development of non-standard equipment suitable for its own professional construction needs, improve the equipment research and development ability of teachers and students, improve the level of laboratory construction.

Key words: Self-research and self-production, Ability to practice and innovate, Flexible stress strain sensor
