Biomimetic Tympanic Membrane Replacement Made by Melt Electrowriting

open access: yesAdvanced Healthcare Materials, 2021
The tympanic membrane (TM) transfers sound waves from the air into mechanical motion for the ossicular chain. This requires a high sensitivity to small dynamic pressure changes and resistance to large quasi‐static pressure differences.
