Figure 6From: Rapid electrocapillary deformation of liquid metal with reversible shape retention Critical oxidation lengths. Critical oxidation lengths for electrochemically actuated liquid metal advancing in a 1 mm x 15 mm x 0.3 mm channel. The images show the maximum length the liquid metal advances into the channel before the oxide formation at its leading edge becomes too rapid to break through. The plot shows the linear relationship between this critical length and the oxidizing actuation voltage.Back to article page
