Embroidering a Filmsy Photo-rechargeable Energy Fabric with Wide Weather Adaptability.

To provide a light and breathable self-charging wearable power source adaptable for various weather conditions and body movements, couching embroidery have been proposed as an industrial-scalable electrode-to-device assembling strategy, rather than a decorative textile pattern making process. Various types of cable electrodes and device units with large size and shape difference were directly and reliably assembled on a light and soft tulle to form either photovoltaic or battery devices, which can be further integrated follows any irregullar pattern and any electrical connection design. Under sunlight, a transparent tulle as a glove or scarf can be charged up at power of 10W/m2, and then maintain a stable power output at dark for various weather and body-move conditions, including bending, twisting, hand-stretching, wind blowing and water washing. Our approaches not only simplified the fabrication of integrated fabric-type energy devices, but also improve the structure and function design flexibility of portable electronic power source, especially for summer wearing applications.
