title: Electrochemical detection of bubble oscillation.
abstract: The interaction of a tethered bubble with sound is demonstrated using novel electrochemical characterisation technology. A 25 microm diameter microelectrode, positioned close to the gas/liquid interface is used to monitor the motion of the bubble wall as a function of time in the presence and absence of sonic irradiation. Evidence for 'breathing' mode oscillation of the bubble and its effect on mass transfer to the microelectrode is presented.
