 '''Magnetic Field Printing<sup>[9]</sup>'''
-Cau et al. demonstrated that perfect reproducibility and homogeneous pressure is capable by magnetic field printing. By creating a second layer of PDMS injected with iron powder, the stamp was able to be manipulated using fully automated equipment utilizing a magnetic field. The field maintains the position of the whole PDMS stamp via the iron powder, and can be adjusted for the size of the stamp features (i.e. decreasing the strength of the magnetic field for larger features to allow some margin of movement and prevent feature damage).
