Abstract
In developing an artificial membrane in a total alloplastic middle ear (TAM) prosthesis (Grote 1984) one of the main research goals is mechanical compatibility (besides biological compatibility). First, micromechanically (≈10-9-10-6m), vibration amplitude spectra in response to sound must match that of the natural membrane in a sufficiently wide frequency range (between 200 and 10000 Hz). Second, macromechanically (≈10-3m), the elasticity modulus must be in the natural range for purposes of epithelial overgrowth and ingrowth. As ingrowth requires a porous material structure, porosity is a relevant structural variable, to be monitored by use of scanning electron micrographs. Finally, the material must sustain sterilization, at a temperature of about 120 °C.
