MXene Enabled Wearable Energy Storage Solutions

E-textiles can create new user experiences and provide comfortable monitoring of patient vitals. To realize their potential, there is a need for textile-based energy storage. However, devices reported in the literature don’t store enough energy to power the electronics necessary to realize this vision. MXenes are conductive 2D materials with an electrochemically active surface and high energy storage capacity that can be integrated into textiles, making them an ideal candidate for textile-based energy storage. We demonstrate the use of MXenes in two different textile-based devices to power fully programable microcontrollers capable of motion tracking and environmental sensing for extended times.
