Animation depicting the motion of the horizonally-oriented DVRT sensor core within the Nano-DVRT sensor as it was mounted by researchers onto the Liberty Bell. As the core moves further into the electrical coils within the block at the base of the diagram, the coils change the manner in which they conduct current. The current change is proportional to the motion, and the device can be sensitive to motions of less than one millionth of a meter.
