Washable, Wearable Battery-Like Devices

Wearable electronic components incorporated directly into fabrics have been developed that could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications. Graphene — a two-dimensional form of carbon — and other related materials can be directly incorporated into fabrics to produce charge storage elements such as capacitors, paving the way to textile-based power supplies that are washable, flexible, and comfortable to wear.
