We present the design project employed in the introductory Biomedical Engineering course in Instrumentation and Design at the University of Auckland. In this course, teams of 5 to 6 second-year students with no prior hands-on experience in mechanical or electronic design work to design hand-held breath alcohol testers based on a simple resistive sensor, in parallel with a sequence of formal laboratory exercises intended to introduce them to electronic and mechanical CAD software, analog electronics prototyping, and software development in LabVIEW. The project reinforces these skills, while also developing skills in specifications development, design iteration, design for manufacturing, and design for assembly. In the context of engineering education in New Zealand, the design project is unusually open-ended, particularly at the second year level: students begin the semester with a given sensor and a prompt to develop a consumer breathalyzer, and must develop detailed design specifications, appropriate designs for 3D-printed housings, suitable signal conditioning circuitry, and a software interface based on their own research. Work is ongoing to achieve the best possible alignment between lecture and practical content in this course, and to obtain data in support of the intended outcomes of the project.
