Liquid metal runs through new flexible circuits

by • February 29, 2016 • No Comments

Before things like touch-sensitive robot skin or prosthetics skin can become tedious, we initially require to create robust and reliable flexible electronics. Researchers of Switzerland’s EPFL research institute have taken a big step in the direction of which goal, by createing circuits which stay functioning while being stretched by up to four times their original length.

These flexible circuits are created of liquid metal, an alloy of gold and gallium. The gallium possesses great electrical qualities, and thanks to a supercooling system, stays in its liquid say actually at room temperature.

The gold keeps the gallium in one continuous homogenous movie, enabling an electrical current to flow through it unimpeded. Without the gold, the gallium may disperse into separate droplets.

The conductive alloy is distributed along nanochannels which have been etched in an elastic polymer substrate. As described, the finished product can be stretched by four times without any interruption in current. It in addition stands up well to being repeatedly folded and twisted.

More information is on the market in the video at a lower place.
