Behavior Analysis of a Ferrofluidic Gyroscope Performances

In this work a gyroscope using a ferrofluidic mass as inertial mass is presented. The device consists of a glass plate filled with deionized water with an injected ferrofluidic drop, a electromagnetic driving system to move the ferrofluidic mass back and forward along the actuation axis and a differential inductive readout system to sense the motion of the ferrofluidic sphere. An angular rate imposed to the device produces a deviation of the ferrofluidic mass trajectory which is measured by the differential readout system. Experimental surveys have been performed to characterize both the driving system and the behavior of the device.
