Learning Outcomes (valid 01.08.2018-31.07.2020): 

After the course, the student can
1. Explain electrical, thermal, dielectric and magnetic properties from classical or quantum world viewpoint
2. Calculate the main parameters of the abovementioned properties for different materials
3. Describe the working principles of smart materials in sensors and actuators
4. Ask critical questions about peers' work and give constructive peer-feedback (opponenting)

 

Content (valid 01.08.2018-31.07.2020): 

The course gives a physico-chemical overview of thermal, electric, dielectric and magnetic properties of solid state materials. Additionally, different types of smart materials (shape-memory alloys, magnetostrictive & piezoelectric materials, electroactive polymers) are discussed, especially in the view of sensor and actuator applications. The course has also a compulsory Term Paper (group) project.
