A typical resonator in an electronic device responds to one signal with one corresponding frequency. An international team of researchers (USA – Argonne National Laboratory, Michigan State University, Florida Institute of Technology, Israel, Sweden) has developed and demonstrated a nonlinear micromechanical resonator which vibrates with a spectrum consisting of multiple frequencies evenly spaced due to the nonlinear mode coupling, in spite of the fact that it is driven by a single frequency. The novel behavior results from a saddle node on an invariant circle (SNIC) bifurcation. The resonator is an ideal test bed to study the dynamic response of SNIC behavior demonstrated in mechanical, optical, and biological systems. It could ultimately help improve such components in a range of electronics and even create devices that mimic biological processes…read more. TECHNICAL ARTICLE
