Theoretical analysis of dendrite formation generated in an electroosmotic flow with variable shape microelectrodes.

In this work, an analytical solution for the hydrodynamic forces that transport silver ions between microelectrodes of axially variable shape is presented. Four different microelectrode shapes were employed to explore the use of passive methods for silver dendritic growth. The results indicate that a fractal microelectrode shape promotes better silver dendritic formation due to lightning rod effect, while in all configurations, a condition of no-contact between dendrites is reached due to an induced pressure field.
