Topological superconductors are one of the most actively studied materialsthese days. They are a promising candidate for hosting Majorana fermions eitheron their boundaries or in vortex cores. Detecting 1D edge current around theperiphery of a 2D $p_x + ip_y$ superconductor would be a hallmark signature oftopological superconductivity, but Majorana fermions are not amenable toelectronic current measurements due to their charge neutral nature. Thermalconductivity measurements, such as thermal Hall effect, are alternativelyproposed, but material synthesis must come first. Superfluid $^3$He-$A$, on theother hand, is a known $p_x + ip_y$ superfluid whose edge current can bemeasured with a gyroscopic technique. Here, we propose a microelectromechanicalsystem based gyroscope that will not only have enough signal sensitivity tomeasure the edge current but also be used to observe dimensionality inducedphase transitions between different topological superfluids.
