At the École polytechnique fédérale de Lausanne, Switzerland researchers have created a new method for making stretchable electronics that may end up being integrated into wearables and medical devices. The prototype films can stretch up to four times their original shape and relax back without suffering any degradation in its electrical properties.
The researchers’ main achievement was achieving in making very narrow wires out of liquid metal (gold/gallium alloy) that bend along with the rest of the film but do not break down into individual pieces.. They’re only a few nanometers in width, and so can be used to connect multiple components within a single larger flexible device.
Here’s more about the new stretchable electronic films:
