Figure 1. The direct writing process of electrical components on paper by using GaIn₁₀-based liquid metal ink.

(A) The detailed dimensions of both in-plane and conventional sandwich patterns of the designed capacitors. (B) The preparation process of both in-plane and conventional sandwich patterns of electrical capacitors are taken for an example. (C) Exploded view schematic illustration of an array of concentric circular patterns of electrical capacitors written in the same plane.
