This activity, from the Institution of Engineering and Technology (IET), is one of a series of activities which explores body centric communications. Students study data and annotate a diagram to show what electromagnetic radiation can penetrate the atmosphere. The activity also looks at the visible/infrared window and a microwave/short wave radio window.
Body centric communications have abundant applications in personal healthcare, smart homes, personal entertainment, identification systems, space exploration and military. This topic investigates the driving technology behind body centric communications, explores current health applications of these devices, possibilities for the future and the ethical issues surrounding these advancements.
