A team of engineers at the Massachusetts Institute of Technology has created a soft, wearable sheet capable of sensing its own three-dimensional shape with precision within half a centimeter in laboratory conditions. The material, detailed in a study published in Advanced Intelligent Systems, uses arrays of optical fibers to detect bending in multiple directions, enabling accurate tracking of movement without reliance on external cameras or rigid components. Researchers noted that the system maintains functionality even when partially damaged, though the fiber thickness currently limits its integration into clothing. Applications under consideration include interactive gaming interfaces, immersive virtual reality environments, and motion monitoring for physical therapy. The development represents a step toward fully soft sensor systems that could expand the range of motion-capture technologies available for consumer and medical use.
