Ear Tissue Biomechanics |
|||
|
The human external ear canal skin (bony part) with eardrum and malleus attached was harvested from cadaver. |
||
Mechanical properties of the external ear canal skin, tympanic membrane (eardrum), three middle ear ligaments and tendons (stapedial tendon, tensor tympani tendon and anterior malleolar ligament) are tested on a computer controlled material testing machine manufactured by TESTRESOURCES Co. |

Typical stress-strain curves of the biological tissue (e.g., eardrum). The hysteresis phenomenon is clearly shown in this figure under loading and unloading. |
