In polydimethylsiloxane. The mixture retains manyproperties of pure PDMS, including moldability, elastic after cured, good adhesion to glass and silicon substrates. And the additivity of iron makes the composite can be magnetically actuated.

Fe-PDMS 为一种混合PDMS（polydimethylsiloxane-聚二甲基矽氧烷）和铁粉的复合材，加入铁的目的在於使其具有感磁，当用Fe-PDMS 制成轻薄的结构时用外加磁场可使其产生型变，能作为微驱动器之材。

To her, it looked like the ink of an octopus.

对她来说，那就像章鱼的墨汁一样。
