Abstract

The mass transfer limitation is one of the major challenges for many electrochemical sensing applications. To overcome this, a piezoelectrically-driven vibrating electrode is presented in this work. CFD and electrochemical testing methods are used to study the effect of vibration on mass transfer properties of the electrode. Mass transfer coefficient enhancement attributed to vibration is observed in the simulation and verified by experiment.
