This technology involves the production of multimaterial fibers having embedded devices with electrical conductors that provide connectivity. The process involves drawing these components into a fiber with a metallurgical bond.

Multimaterial fibers with embedded electronic devices are highly desirable in numerous industries as a core component of smart textiles and microsensors. However, ensuring reliable electrical connectivity and resistance to mechanical stress within the fiber structure has posed significant challenges. The conventional methods often disrupt the fiber integrity and limit their functionality. Existing solutions that typically involve wrapping fibers around the devices can compromise durability and conductivity. Other approaches involve embedding devices into fibers, but these solutions struggle to maintain consistent electrical contact, resulting in intermittent connectivity. Hence, there's a strong need for innovative methods of embedding devices in fibers that would solve these issues.

Technology Description

This technology is a method to manufacture multimaterial fibers with integrated electrically connectable devices. Such devices are strategically positioned within a pocket of a preform material with an electrical conductor arranged longitudinally in a conduit within the material. The process draws the multimaterial fiber such that the conductor aligns within the fiber along its longitudinal axis, making contact with an electrode on each integrated device. The unique differentiation of this technology lies in the formation of a metallurgical bond between the first electrical conductor and the electrodes during the fiber drawing process. Additionally, after the fiber has been drawn, the electrical conductor is situated substantially along the neutral axis of the fiber. This structure enhances electrical connectivity and offers potential in numerous applications for which strong, flexible, and electrically conductive fibers are required.
