摘要:
A passive nanomagnet alignment method is described to self-align a membrane to another surface. The membrane and the surface each have a plurality of nanomagnets patterned on it, wherein the nanomagnets are magnetized based on an applied external magnetic field. The membrane is brought into close proximity and coarse alignment to the surface by a positioning mechanism (e.g., an actuation force), such that the nanomagnets on the membrane attract to and self-align with the nanomagnets on said surface based on the nanomagnet magnetizations.
