We’ve talked about different materials engineers use to build things in the world, but there’s a special category of materials they turn to when building things to go inside our bodies. In this episode we’ll explore the world biomaterials like titanium and their coatings, the special chemistry of polyurethane, and the cross-linked structure of hydrogels. We’ll also look at the importance of safety & research, as well as the enormous future potential of biomaterials.
Students examine the structure and function of the human eye, learning some amazing features about our eyes, which provide us with sight and an understanding of our surroundings. Students also learn about some common eye problems and the biomedical devices and medical procedures that resolve or help to lessen the effects of these vision deficiencies, including vision correction surgery.
Human beings are fascinating and complex living organisms a symphony of different functional systems working in concert. Through a 10-lesson series with hands-on activities students are introduced to seven systems of the human body skeletal, muscular, circulatory, respiratory, digestive, sensory, and reproductive as well as genetics. At every stage, they are also introduced to engineers' creative, real-world involvement in caring for the human body.
We’ve discussed the four main branches of engineering but there are so many other fields doing important work, so today we’re going to explore a few of them. In this episode we’ll explore some of the history and fundamentals of industrial engineering, biomedical engineering, and bioengineering.
