In the teaching of RCL, circuit experiment, students are guided to think about the origin olmemristor, In view of the outstanding problems in memristor teaching, device performance is mainly simulated, and testing is dependent on the expensive semiconductor analyzer, Based on the scientific research and experimental teaching, the authors prepared the memristor with a AgNW/AgNP-PVP/AgNW sandwich structure , built a simple test circuit, and demonstrated the conduetive charaeteristics of the memristor Combining the frontier research with the reform of experimental teaching, the designed research experiments eultivate students’ innovative thinking and praetical ability. The seientilie research feeds teaching, and benelitsteachers and students.
