Abstract

Transparent and flexible loudspeakers are realized with large-area monolayer graphene. The acoustic performances are characterized according to the supporting substrate effect and geometrical configurations. The substrate effect on the thermoacoustic sound generation from graphene is studied by controlling the surface porosity of various substrates.
