Figure 10. Reversible shape and charge redistribution mechanism of liquid metal, reproduced with permission from Zhang et al.[43]. (A) Experimental schematic diagram and equivalent circuit after applying DC power. (B) Experimental schematic diagram and equivalent circuit without external power supply. (C) Effect of surface oxide layer on droplet morphology. (D) Change process of droplet shape when the external power supply was removed after 5 s.
