| Summary: | NEMS Resonators: Achieving strong internal resonance Achieving strong ‘internal resonance’ within a simple nanoelectromechanical resonator opens doors to further research and practical applications. Hanna Cho, and a team from The Ohio State University and Michigan State University, United States, describe in their new paper how internal resonance (IR) offers a “unique pathway” to steer vibrational energy, with applications in signal detection and simultaneous physical property sensing. Robust achievement of IR has proved challenging, with the property first realized in the early 2010s. The team now describe the robust generation of IR by a “relatively simple” nanoelectromechanical resonator, and the design parameters that can be manipulated to alter resonance behaviors. The team hope that their blueprints can act as a stepping stone for deeper investigation into the exploitation of IR for various applications.
