Abstract :
In this paper an inertial sensor based on the effect of an unknown perturbation on the movement of a ferrofluid spike is presented. The device consists of a glass beaker filled with deionized water and a spike shaped mass of ferrofluid. A suitable magnetic field configuration is exploited to force a spike shape to the ferrofluid. The movement of the spike free-end is sensed via an InfraRed readout strategy. A description of the adopted experimental set-up is given along with some experimental results.
