Researchers develop wireless charging system for smart textiles

Researchers from Drexel University, the University of Pennsylvania, and Accenture Labs have developed a wireless charging system for textiles. This new textile energy grid can power devices like warming elements and sensors without the need for bulky batteries. The grid is made from a conductive MXene ink printed on flexible cotton. It includes a resonator coil for wireless charging and supercapacitors for energy storage. This system can charge devices efficiently, providing power for over 90 minutes after just 15 minutes of charging. The technology also supports various applications, including health monitoring and environmental sensing. Future work will focus on scaling the system while maintaining its performance and integration into textiles.
