Magnetic properties of materials for MR engineering, micro-MR and beyond
Matthias C Wapler, Jochen Leupold, Iulius Dragonu +3
We present the results of a systematic measurement of the magnetic susceptibility of small material samples in a 9.4 T MRI scanner. We measured many of the most widely used materia…
A new dimension for piezo actuators: Free-form out-of-plane displacement of single piezo layers
Matthias C Wapler, Jens Brunne, Ulrike Wallrabe
We present a controlled mode of "topological" displacement of homogeneous piezo films that arises solely from an inhomogeneous in-plane strain due to an inhomogeneous polarization.…
Piezo films with adjustable anisotropic strain for bending actuators with tunable bending profiles
Matthias C Wapler, Moritz Stürmer, Jens Brunne +1
We present a method to produce in-plane polarized piezo films with a freely adjustable ratio of the strains in orthogonal in-plane directions. They can be used in piezo bending act…
