= Acousto-electric effect
{wiki=Acousto-electric_effect}
The acousto-electric effect refers to the phenomenon where an acoustic wave (sound wave) generates an electric voltage or current in a material. This effect can occur in certain piezoelectric materials—substances that generate an electric charge in response to applied mechanical stress. When sound waves propagate through such materials, they exert varying mechanical forces, leading to charge separation and creating an electrical signal.
