Research Experiment Design of Wearable Sensors in Medical Physics Experimental Course

Integration of medicine and engineering is an important path for Chongqing University to explore the cultivation of new medical students in recent years. Based on medical physics experimental course, a research experiment was designed and implemented to develop a flexible wearable sensor utilizing triboelectric nanogenerator technology. The goal is to establish a closed-loop pathway of “teaching–research–teaching” in the cultivation. Starting from a practical application scenario of monitoring neck movements, a fully silicone-based flexible triboelectric sensor was designed using a single-electrode mode. A simplified model was developed to investigate the influence of human body electric potential on sensor performance, and a corresponding shielding layer design was proposed. Through experimental implementation and result discussions, students were guided to explore scientific problems and develop research-oriented thinking. This experiment provides both valuable materials and a practical teaching model for enhancing the physical science literacy of medical students, offering meaningful insights into interdisciplinary talent training under the framework of medicine–engineering integration.
