New Process Can Print Stretchy Electronics Onto Your Clothes

TechCrunch

Researchers at the University of Tokyo have created a single-step process to print conductive material on cloth, allowing manufacturers to build stretchable wearables that can test vital signs like heart rate and muscle contraction.

From the release:

Now, Professor Takao Someya’s research group at the University of Tokyo’s Graduate School of Engineering has developed an elastic conducting ink that is easily printed on textiles and patterned in a single printing step. This ink is comprised of silver flakes, organic solvent, fluorine rubber and fluorine surfactant. The ink exhibited high conductivity even when it was stretched to more than three times its original length, which marks the highest value reported for stretchable conductors that can be extended to more than two and a half times their original length.

Why is this important? Because it allows for the traces to and from electronic components to be amazingly stretchy. While components like…
