Abstract : In this paper we discuss the existence and stability of heteroclinic cycles in coupled systems and show how they can be exploited to design and fabricate a new generation of highly-sensitive, low-powered, sensor devices. More specifically, we present theoretical and experimental proof of concept that coupling-induced oscillations located near the bifurcation point of a heteroclinic cycle can significantly enhance the sensitivity of an array of magnetic sensors. In particular, we consider arrays made up of fluxgate magnetometers inductively coupled through electronic circuits.
