FIG. 1.

Basic device diagrams and operation (left) and photographs of demonstrations (right) of several liquid metal logos interconnected with a liquid metal mesh pattern.

FIG. 2.

Required Laplace pressure to move liquid metal of γ = 0.5 Nm−1 into a trench as a function of scaling the trench dimensions (x). One psi is equal to 6894.8 Nm−2.
