    Abstract

    In this paper, a new, simple method to determine dynamic surface tension in aqueous solutions is reported, explained and experimentally verified. By function integration, a small device is obtained; apart from control and interface electronics no external components or systems are necessary. Instead of the conventional sparging, we use the (cathodic) electrolysis of water at an actuator to produce gas bubbles in situ. The actuator can also function as the sensor for the bubble frequency by monitoring either its overpotential or its impedance
