Abstract: As the digital transformation of public health accelerates and the demand for emergency response surges, preventive medicine education urgently needs to integrate technological innovation in response to global health challenges. This paper proposes leveraging wireless body area network (WBAN) technology to innovate the teaching mode of preventive medicine (focusing on intelligence and emergency response), provides an in-depth argument for its pedagogical suitability, and, drawing on teaching cases, systematically designs an instructional application plan. The plan covers implementation pathways, key issues and countermeasures, expected outcomes, and evaluation mechanisms, with the aim of enhancing students’ capabilities in applying intelligent technologies and responding to emergencies, thereby offering an innovative pathway for cultivating top-notch interdisciplinary talents in public health.
