Introducing electrical engineering through characterization of a handheld moisture meter: A research experience case study

Concepts from electrical engineering can be introduced to nonmajor engineering students through lectures, laboratories, or even research experiences. Often the purpose of introducing nonmajors to these concepts is to highlight that engineering problems are not limited to skills from only a single discipline as well as improve their ability to communicate and collaborate with other disciplines. This case study discusses the experience of introducing a nonmajor undergraduate student to electrical engineering through an undergraduate research project at The University of Alabama investigating the electrical properties of bamboo, which required the characterization of a portable moisture meter. These exercises were successful at improving the student’s confidence and proficiency with electrical test equipment, highlighting the limitations of test equipment, and applying concepts of resistance to a real-world application that overlaps electrical, chemical, and biological disciplines. While this exercise was a component of an undergraduate research experience, similar exercises could be easily integrated into electrical engineering laboratories for nonelectrical engineering majors to introduce and reinforce concepts from electrical engineering using a multidisciplinary application
