MXene-enabled textile-based energy grid utilizing wireless charging

Abstract

As the Internet of Things (IoT) expands, electronics will take on new form factors. With the ubiquity of textiles in our daily lives, integrating functionality into them is a promising proposition. Realizing a future with textile-based electronics (e-textiles) will require on-textile power supplies. Due to their high conductivity, electrochemically active surface, and ability to produce additive-free coatings from aqueous inks, MXenes are an ideal material to integrate into textiles to add functionality as well as generate and store electrical energy. Herein, we demonstrate an on-garment energy grid utilizing MXenes in textile-based supercapacitors and wireless chargers. Our on-garment energy grid can power real-world electronics, including peripheral electronics performing environmental sensing and data transmission, including an all-MXene surface electromyography (sEMG) sensor with real-time data transmission. Finally, we create a fully wireless textile-MXene joule heater directly powered by our MXene coil.
