Motivation
- Conventional damper:
- Limited down-scaling
- Incompatibility with MEMS process flow
- SMA foil damper :
- High dissipation energy
- High work density
- Large stress range
- Accomodation of large strain
- MEMS batch fabrication possible
Research Goals
- The design of enhanced active or passive damper systems allowing for vibration control with respect to two (2D) and three (3D) loading directions
- The development of a fabrication process for the 2D and 3D damper systems based on state-of-the art microtechnology
- The extension of the experimental 1D test setup for the characterization of the 2D and 3D damper systems
- The extension of the simulation model describing complex 2D and 3D loading cases in SMA film devices showing the SE, SME or both
- The experimental characterization and simulation of the performance properties of different design variants of 2D and 3D passive and active damper systems
- The development and assessment of mixed active /passive damper systems
- The integration of temperature and acceleration sensing as well as intrinsic position sensing for smart damping
