Textile Energy Storage

Super-capacitors made with activated carbon material

This research focuses on electrical energy storage solutions for textiles and wearable electronics, a fundamental challenge for designers of smart textiles and wearable technology. As a solution to this problem, we are focusing on super-capacitors made with activated carbon material. When combined with low power energy harvesting devices, such as power supply, they can eliminate the need for batteries in applications like wireless sensor networks. In our previous work, we screen printed woven cotton and polyester electrodes with activate carbon as proof of concept for a textile super-capacitor. We are currently investigating the incorporation of spun carbon fiber yarn into a knit architecture to fully integrate super-capacitor devices directly into textiles.

The Capacitive Touch Sensor (CTS) is a gesture sensitive functional textile touch-pad interface for physical devices. The CTS is produced as a single piece of fabric requiring only two electrodes to connect it to a microcontroller. The CTS offers a solution for a flexible touch interface with consistent location detection, responsiveness, comfort and unobtrusiveness. Contact us at for more information.
