Abstract

Systems and methods are provided for providing vibration transduction and radio-frequency communication in proximity to an electrically conductive structure. The system may comprise an antenna element, an electrically conductive structure in proximity to the antenna element, and a vibration transducer comprising a material. The material may comprise a ferromagnetic material with piezoelectric properties. The vibration transducer may be positioned between the antenna element and the conductive structure.
