This module demonstrates a tool to help students understand the general process of development of medical devices from concept to market. This module will focus on a vital sign monitoring system as a case study. This module can be used in junior/senior undergraduate courses including a term project in biomedical engineering. It will guide students to design a prototype with an Arduino kit, prove its concept and function, and figure out its potential use in a market. They will use an Arduino kit with ECG and SPO2 sensors to measure heartbeat rate, its pattern, and SPO2 value. Thus, students will have opportunities to design/fabricate/test a prototype of a medical device, survey market needs, and study necessary regulations associated with FDA guidance and quality systems. This module will also help students develop their entrepreneurial mindset with curiosity, connections, and creating value.
