Abstract:	A new method is proposed for the measurement of dynamic surface tension in aqueous solutions. The advantage of this method with respect to the classical method based on sparging is that the use (of gas pumps is avoided, resulting in a miniaturised system. This method is based on the in-situ generation of gas bubbles by means of electrolysis at Microcavity Electrodes (MCE). As a consequence of electrode surface shaiping, a single nucleation site for gas bubbles is created. The MCE is used simultaneously as a bubble actuator (generator) and as a bubble size andlor frequency sensor. Measurement results prove the suitability of the electrolytical method for the monitoring of the dynamic surface tension in aqueous solutions.
