Abstract
Graphene woven fabrics (GWFs) consisting of a large number of overlapping graphene micro-ribbons were fabricated by chemical vapor deposition. We demonstrated that GWF films can emit sound efficiently once they are actuated by a sound-frequency electric field owing to the thermoacoustic effect. Because of its ultra-low heat capacity per unit area, the GWF shows sound generation performance comparable to single-layer graphene and carbon nanotubes, and would perform better than them when it is suspended on a high porosity substrate. This sound source can be used in a wide variety of applications, taking advantage of its transparency, flexibility, ultrathin nature, absence of moving parts, and biologically compatible characteristics.
