Abstract: A cartilage conduction system may include (1) a transducer that generates mechanical energy and (2) a functionally graded material (FGM) interface dimensioned to be coupled between the transducer and cartilage located on an outer ear of a user, wherein the FGM interface (1) exhibits a gradation of at least one characteristic from one side of the FGM interface to another side of the FGM interface and (2) facilitates transferring the mechanical energy across the gradation of the characteristic from the transducer to the cartilage. Various other systems and methods are also disclosed.
