Query: Liquid Metal Enabled Droplet Circuits   Conventional electrical circuits are generally rigid in their components and
working styles which are not flexible and stretchable. From an alternative,
liquid metal based soft electronics is offering important opportunities for
innovating modern bioelectronics and electrical engineering. However, its
running in wet environments such as aqueous solution, biological tissues or
allied subjects still encounters many technical challenges. Here, we proposed a
new conceptual electrical circuit, termed as droplet circuits, to fulfill the
special needs as raised in the above mentioned areas. Such unconventional
circuits are immersed in solution and composed of liquid metal droplets,
conductive ions or wires such as carbon nanotubes. With specifically designed
topological or directional structures/patterns, the liquid metal droplets
composing the circuit can be discretely existing and disconnected from each
other, while achieving the function of electron transport through conductive
routes or quantum tunneling effect. The conductive wires serve as the electron
transfer stations when the distance between two separate liquid metal droplets
is far beyond than that quantum tunneling effects can support. The unique
advantage of the current droplet circuit lies in that it allows parallel
electron transport, high flexibility, self-healing, regulativity and
multi-point connectivity, without needing to worry about circuit break. This
would extend the category of classical electrical circuits into the newly
emerging areas like realizing room temperature quantum computing, making
brain-like intelligence or nerve-machine interface electronics etc. The
mechanisms and potential scientific issues of the droplet circuits are
interpreted. Future prospects along this direction are outlined.
