DuPont Microcircuit Materials has developed a line of stretchable electronic ink materials for use in smart clothing applications and other wearable electronics.

The materials are designed to provide an elegant, manufacturing-ready alternative to traditional methods of embedding electronics in clothing.

The DuPont materials have been used to create thin, form-fitting circuits that can be bonded with many standard fabrics, allowing for comfort and freedom in wearable electronic design.

"We believe that this new line of DuPont stretchable electronic inks can be used in wearable electronics applications to make clothing more capable and comfortable," said Michael Burrows, segment manager, DuPont Microcircuit Materials.

The stretchable electronic inks deliver stable performance despite repeated elongation, says DuPont. A third party evaluation of fabrics that incorporate these materials to create thin electronic circuits have shown them to be washable, durable, and capable of withstanding up to 100 wash cycles, it added.

DuPont plans to offer a full material suite of conductors, encapsulants, and sensors for use in wearable electronics applications, including: DuPont PE872 stretchable conductor, which is washable with encapsulation; and DuPont PE772 stretchable, washable dielectric encapsulant.
