Chemistry Year 12 - Module 8 - Lesson 18
Biomaterials & Smart Materials
1. Key Ideas
A nitinol stent can be compressed for insertion into an artery and then recover its working shape at body temperature. That sounds almost futuristic, but it is really a chemistry-and-materials story about how composition and structure can be chosen so that a material interacts productively with a living system or responds to a stimulus in a useful way.
- The definitions of biomaterials and smart materials
- Why biocompatibility and response to stimuli matter in design
2. Success Criteria
By the end, you should be able to:
- The definitions of biomaterials and smart materials
- The named biomaterial and smart-material examples in the course
- The key stimuli that can trigger smart-material behaviour
3. Key Terms

5. Short Answer Questions
1. Explain this lesson goal in your own words: "The definitions of biomaterials and smart materials". Use one specific example from the lesson.
2. Apply this idea to a new example: "The named biomaterial and smart-material examples in the course". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Biomaterials & Smart Materials: "The key stimuli that can trigger smart-material behaviour".
6. Extend: Apply the Idea
A student gives a memorised answer about Biomaterials & Smart Materials but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
