Printed MXene coils on textiles for wireless charging and energy storage
A system and method of manufacturing MXene-based coils on textile substrates. The system and method enable wireless charging of embedded devices in textiles, including energy storage, sensors, and wireless charging coils, removing the need for rigid physical connections. The systems manage print content by deposition of MXene ink compositions with a custom-generated coil design comprising specific geometric parameters that are configured to target required performance targets. Such an approach allows for the augmentation of e-textiles with sufficient energy and/or data transmission capacities so as to support the use of a wide range of smart devices and applications.
