The Impact of Location and Device Coupling on the Performance of the Osia System Actuator

Figure 8

Velocity of the cochlear promontory when stimulating the skull with an actuator coupled with a BI300 bone screw. Results are shown for the four specimens, with different colors illustrating different test cases to simulate reactive bone undergrowth. Magnitudes are plotted together with error bars. The response when partially or completely cemented differ significantly from the no cement condition at most frequencies (). Exceptions in the comparison between partial and no cement are observed for Head 16 at 0.75 and 3 kHz (). Exceptions in the comparison between complete and no cement are observed for Head 15 at 1 and 3 kHz ( and , respectively) and for Head 16 at 0.75 and 2 kHz ( and , respectively).
