Making Robots and Wearable Technology Better With ‘Stretchy Circuits’

by | | 0 comment(s)

Recently, Swiss researchers discovered and created thin electronic circuits that can be stretched up to four times their original length. These circuits can be stretched millions of times before cracking or losing conductivity. With such flexibility, this discovery is ideal for biological sensors, artificial skin, prosthetics, and even smart clothing.

This material is made by using both liquid metals and solid metal alloys. The film is composed of both gold and gallium. When stretched, cracks can form in the solid gold alloy but they are quickly filled by liquid gallium. The final material can be lithographed onto all surfaces in complex patterns like average electronic circuits.
