Abstract—The change in the current in an electrochemical cell is studied simultaneously with the dynamics and
luminescence of a solitary cavitation bubble produced by focusing a shock wave near a disk anode 0.6 mm in
diameter in an NaCl solution. The current is maximum at the instant of the bubble collapse. The increase in the
current is due to the mass transfer near the electrode intensified by the hydrodynamic flow around the bubble.

Key words: bubble, cavitation, collapse, shock wave, sonoelectrochemistry
