By incorporating a special type of plastic yarn and using heat to slightly melt it — a process called thermoforming — the researchers were able to greatly improve the precision of pressure sensors woven into multilayered knit textiles, which they call 3DKnITS.

The materials, embeddable electronics, and fabrication machines have advanced enormously since then,” Paradiso says. “It’s a great time to see our research returning to this area, for example through projects like Irmandy’s — they point at an exciting future where sensing and functions diffuse more fluidly into materials and open up enormous possibilities.
“The thermoforming really solves the noise issue because it hardens the multilayer textile into one layer by essentially squeezing and melting the whole fabric together, which improves the accuracy. That thermoforming also allows us to create 3D forms, like a sock or shoe, that actually fit the precise size and shape of the user,” he says.
