Abstract: The integration of digital technology into everyday life has been a long-standing human pursuit. Currently, wearable electronic skins emerged as a transformative innovation have been widely used in human motion monitoring, healthcare, and artificial intelligence. To explore an interdisciplinary talent cultivation model that merges chemistry, chemical engineering, and biomedical sciences, gellan gum/polyacrylamide dual network hydrogel was fabricated and applied as flexible sensor to monitor human movement and physiological signals. The experiment combines the published research work in our group with undergraduate teaching experiments, and introduces the E-skin to students from preparation method to its practical application, stimulating students’ interests in learning and innovation.
