Electromagnetically excited resonator sensors for remote mass detection and liquid phase sensing

Abstract

Electromagnetic excitation of acoustic resonator sensors is a novel method with distinct advantages over piezoelectric resonators. A much wider range of transducer materials can be utilized, and remote excitation of resonant vibrations in a wide variety of different mode shapes is possible. These resonant modes display similar quality factors and characteristics as piezoelectric transducers and can be applied for mass detection and liquid phase sensing.
