Fig. 2. Demonstrations of PLEEC.

Fig. 2

(A) Asymmetric capacitors with different shapes. The lower electrodes have double the widths of the upper electrodes. When the voltage is on, the liquid is trapped within the patterned region of the lower electrodes. (B) Liquid pattern in the shape of an angry bird. (C) Liquid pattern of four letters “X,” “J,” “T,” and “U.” (D) Liquid patterns of nine natural numbers by independently controlling line pixels. (E) Changeable liquid patterns in the same PLEEC panel by independently controlling 10 × 10 pixels. (F) Liquid patterns of four representative hydrogel precursors with different chemical and physical properties and polymerization into hydrogel by different polymerization methods. (G) Liquid patterns of four functional materials: temperature sensitive, biocompatible, ionically conductive, and molding materials. Photo credit: Jikun Wang, Xi’an Jiaotong University.
