Nitinol in der Medizintechnik

Location: Technische Akademie Esslingen (An der Akademie 5)

The seminar will focus on key performance attributes of Nitinol.
 

The seminar will provide design guidelines for Nitinol components with consideration of fatigue and durability, biocompatibility and corrosion, MR compatibility as well as manufacturing aspects. Additionally, aspects of the additive manufacturing of Nitinol will be addressed.
