Abstract

This talk considers electrochemistry and acoustics and how they may be linked: It starts by reviewing acoustic sensing devices and effectives strategies that underpin many of the acoustic biosensors and bioanalytical methods that are in use today. Continues with the many different types of acoustic geometries that can be used to trap and levitate particles (eg algae, cells and viruses) within acoustic filters, which are highly desirable non-clogging components for particle processing. And then considers how these acoustic geometries have the potential to perform self-assembly functions and in some cases create acoustic wave fields that can generate a metamaterial forms. Finally the talk introduces the history of the solion device together with more recent evidence that these electrochemical systems operate as highly responsive acoustic sensors with better performance than MEMS devices.
