Smaller, More Efficient Resonating Inductor for Powering Electronic Devices

Increases Power Storage Capabilities of Compact Devices

This microelectromechanical inductor features an unprecedented capacity for energy storage relative to its size. The market for microelectromechanical systems (MEMS) is projected to exceed $28 billion by 2024. Inductors are passive electrical components that use magnetic fields to store energy. Because magnetic inductors are among the bulkiest and least efficient components in electrical systems, they make it difficult to meet the growing demand for smaller and more portable electronics and biomedical devices. Available smaller inductors result in substantial power losses, forcing device designers to decide between energy capacity and portability.

Researchers at the University of Florida have developed a small, highly efficient MEMS inductor that powers electronic circuits. This inductor minimizes energy losses and lasts longer between charges.



A more efficient inductor that makes small, portable electronic devices more powerful and last longer between charges



  • Increases power capacity, expanding device functionality
  • Decreases device size and weight, addressing a growing market need for smaller and lighter devices
  • Lasts longer between charges, boosting convenience


This microelectromechanical inductor makes small electronic devices more powerful and efficient without compromising portability and convenience. The resonating inductor enables high-density energy storage by using electromechanical coupling between an electrically-conducting inductive element and a mechanical resonator. It stores energy passively through both electromagnetic and mechanical mechanisms. The inductor enables even greater electronic miniaturization, enhancing small-scale devices’ usability and convenience.
