Teijin e-stitch sensors used in ladies’ wear
e-stitch, a series of fashionable piezoelectric wearable sensors with stitch designs that measure body motions, has been developed by the fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan, and Professor Yoshiro Tajitsu of Kansai University, Osaka/Japan. Soft, flexible e-stitch sensors, which measure body motions such as extension, contraction, bending and twisting, are largely unrestricted in terms of fabric types and embroidery patterns, allowing them to be produced in highly fashionable designs.
The technologies embodied in e-stitch sensors represent a break from preconceived ideas about wearable sensors because they offer new levels of sensing convenience and fashion.
Going forward, Kansai University and Teijin will continue to explore the potential of polylactic-acid (PLA). Through industry-academia collaborations, they aim to create highly added-value sensing technologies for augmented-reality applications in the Internet of Things.
e-stitch sensors were exhibited at the 4th Wearable Expo in Tokyo from January 17-19, 2018, the world’s largest exhibition of wearable devices and products.
