The purpose of this project is to develop an automated larynx model for patient education. We developed a movable plastic and gypsum-based Plaster of Paris framework controlled by motors and cables, and added silicone muscles to mimic laryngeal anatomy. Our tests indicate that this model improves comprehension of the larynx anatomy and function by 36%. In the future, we hope to further develop this model by both improving its realism and increasing its movement capabilities.
We are currently working on our final report.
