Electronic textiles, also known as e-textiles or garment devices [1] have found a variety of applications in the military and medicine as wearable sensors to monitor soldier or patient vitals, as well as in athletic garments to give real-time feedback to athletes on their performance. However, many of these garments require a power source, such as a battery, but have thus far only integrated conventional coin cell or pouch cell batteries into the fabric.

This seminar provides an overview of the advances made in the field of wearable energy storage, specifically pertaining to batteries or electrochemical capacitors made as fabrics and yarns. A concept garment incorporating energy storing components can be seen in Figure 1.

The field can be categorized into three main thrusts: (1) coated textile energy storage, (2) fiber or yarn energy storage, (3) custom textile structures that incorporate energy storage. Each approach has its advantages, where coating pre-existing textiles with energy storing materials means pre-made garments can be outfitted with new technology. Fibers and yarns that can act as energy storage devices can be woven, knitted or stitched into full fabrics, meaning they have the potential to be embedded into many different kinds of garments. Lastly, custom designing knitted structures that incorporate all the components of energy storage devices give engineers the advantage to design fabrics with specified power and energy densities.  Thispaper also explores systems that combine capacitive touch sensors and energy storage.
