This paper presents the concept, theory, and demonstration of electromechanical inductors that couple an electrical conductor with a mechanical energy storage component in order to boost the electrical inductance over a specific frequency band. Measurements of mesoscale prototypes indicate an inductance boost >10,000x compared to static electrical devices. The results here are a step toward ultra-high-inductance-density microfabricated devices intended to dramatically reduce the size and mass of switched-mode power supplies.
