Abstract
Conveying bioengineering disciplines is challenging given younger students' limited understanding of engineering. While electromyography (EMG) signal model exist mainly when studying sports-related activities, there is no simple model for an entry-level student to understand who does not have prior knowledge. Our design exemplifies the basics of how electromyography signals are captured and turned into code that is used to power an electrical robot arm through a software called BioPac Student Laboratory. Our system consists of two interconnected breadboards,, each incorporating two EMG signal processing channels designed with IC148 logic gates. The circuit will be powered by +-5V and include key components such as capacitors (C21, C22, C23, C26) and resistors (R25-R374). The expected outcome of this research is to provide an approachable introductory hands-on experience to EMG technology, which will inspire interest in biomedical engineering and highlight the department's work in signal processing.
