A highly sensitive graphene woven fabric strain sensor for wearable wireless musical instruments

Highly flexible and sensitive strain sensors are essential components of wearable electronic devices. Herein, we present a novel graphene woven fabric (GWF)/polydimethylsiloxane (PDMS) composite as a highly flexible, sensitive strain sensor capable of detecting feeble human motions with an extremely high piezoresistive gauge factor of 223 at a strain of 3% and excellent durability. A wireless wearable musical instrument prototype made of the composite sensor demonstrates conversion of human motions to music of different instruments and sounds.
