During PhD, I worked on the development of deformable mirrors based on the actuation of a magnetic liquid (ferrofluid). Ferrofluids are liquids that contain ferromagnetic particles of 10-nm average diameter dispersed in an oil or water-based carrier. When a ferrofluid is in the presence of a magnetic field, the ferromagnetic particles align themselves with the field gradient and the surface of the liquid changes to minimize the system energy. Details about this technology can be found in some of the publications listed on this page.
Below is a video showing a 37-actuator magnetic-liquid DM running in closed-loop in our lab.
