Microstructure Innovation in Resistive Gas Sensors: A Pathway to Deepening the Integration of Scientific Research and Undergraduate Education
摘要: 本文探讨了微结构创新在电阻式气敏传感器领域的发展，并基于此设计了一个面向本科生的光电综合训练教学模块，重点培养学生的创新思维与科研实践能力。该模块以具有微结构创新的电阻式气敏传感器为核心研究对象。通过光学显微镜、扫描电子显微镜、拉曼光谱、X射线衍射等技术，学生掌握了材料基本物理性能的表征方法。利用气–湿敏综合测试系统，学生获取了传感器对乙醇的气敏响应数据，并进一步对传感器的性能提升机理进行了深入分析。本教学实践以教师的科研成果为基础，采用“引导式探究学习”的模式，引导学生独立完成器件制备、性能测试与结果分析的全过程，有效促进了科研成果向本科教学的深度转化，显著加深了学生对电阻式气敏传感器原理、工艺及应用的理解。
Abstract: This paper explores recent advances in the development of resistive gas sensors through microstructural innovation and, building on this foundation, designs an integrated optoelectronics training module for undergraduates, with an emphasis on cultivating creative thinking and practical research skills. The module takes resistive gas sensors featuring microstructural innovations as its central subject of study. Students are introduced to characterization techniques for basic material properties using optical microscopy, scanning electron microscopy, Raman spectroscopy, and X-ray diffraction. With the aid of a combined gas- and humidity-sensing test system, they collect sensor response data for ethanol and carry out an in-depth analysis of the mechanisms responsible for performance improvement. Grounded in the instructors’ research achievements, this teaching practice adopts a guided inquiry-based learning model that enables students to independently complete the entire process of device fabrication, performance testing, and result analysis. It effectively promotes the deep translation of research outcomes into undergraduate teaching and significantly enhances students’ understanding of the principles, fabrication processes, and applications of resistive gas sensors.
