Purdue university are using a conventional sewing machine to produce electronics that can stretch. Using wires thin enough to be fed into a sewing machine and a zig-zag pattern electronics that can stretch up to 5 times, in one direction, is possible. This is interesting for electronic fashion as it has been difficult to place electronics on stretchy fabrics. This work is still in the research labs, so I’m guessing it will still be a while before we can make use of the work.
The following photo shows the structure in full stretch.
