Abstract

A carbonized plain-weave silk fabric is fabricated into wearable and robust strain sensors, which can be stretched up to 500% and show high sensitivity in a wide strain range. This sensor can be assembled into wearable devices for detection of both large and subtle human activities, showing great potential for monitoring human motions and personal health.

Keywords: carbonized silk fabrics; graphitic nanocarbon; strain sensors; wearable devices; woven structures.
