摘　　要：摩擦纳米发电技术是一种全新的能源技术和自供能传感技术。将摩擦纳米发电技术引入本科物理实验教学,以一项构造简洁、材料易获取的新型摩擦电眼动传感器研制成果转化为研究性实验项目为例进行了实验教学设计。该实验采用摩擦纳米发电机结构设计中基本的单电极模式,设计制作眼部运动触发的自供能传感器,将其粘贴在眼镜架镜腿内侧,即可将眼角微运动转换为电信号,用于眼动打字等人机交互系统;并辅以物理学术竞赛“自主研究+辩论交流”教学模式,将学科前沿研究与教育教学改革活动整合,培养学生实践创新综合能力,激发教师教学活力,形成科研与教学的有效融合和相互促进。Triboelectric nanogenerator is a new technology of energy and self-powered sensor.This paper introduces the triboelectric nanogenerator into the undergraduate physics experiment,the research result of a new triboelectric eye-movement sensor with simple structure and pragmatic materials is transformed into a research experiment.This experiment adopts the basic single-electrode mode in the structural design of triboelectric nanogenerator,designs and manufactures a self-powered sensor triggered by eye movement.When pasted on the inner side of the leg of the glasses frame,the sensor can convert the micro movement of the corners of eyes into electrical signals for human-computer interaction systems such as eye movement typing.With the teaching mode of“independent research and debate communication”of China Undergraduate Physics Tournament,this program integrates the updating research with education reform,cultivates students’comprehensive ability of practice and innovation,invigorates teachers’teaching,and last forms an effective integration and promotion of research and teaching.
