A biomedical engineering student is seeking innovative project ideas for graduation. Suggestions include developing a portable EEG monitor akin to an ECG, and an app for measuring iron levels in the skin. There is discussion about using x-ray spectroscopy for accurate skin iron measurement and the potential of a device that measures carotene, which could indirectly indicate iron levels due to iron's oxidative effects. Another idea involves using polymers, specifically lecithin, to reduce infection on medical device surfaces, as lecithin may bind metal ions required for infections. The conversation emphasizes the importance of aligning project ideas with personal interests and passions to ensure motivation and success throughout the project.
