// Anatomical feasibility and experimental evaluation of sensor coupling sites for fully implantable active middle ear implants
本研究評估將壓電感測器接合於鼓膜錘柄（umbo）與鐙骨銜接節（incudostapedial joint）於中耳植入的解剖適用性及效能｜分析101耳與顳骨實驗結果顯示，鼓膜錘柄適用率達71%，感測靈敏度與回饋效果與鐙骨銜接節相當｜發現間隔物剛性與接觸力影響靈敏度，低預張力下穩定性最佳，支持鼓膜錘柄作為中耳感測器植入的新穩定接合點。
// This study assessed the anatomical feasibility and performance of piezoelectric sensors coupled to the umbo versus the incudostapedial joint in middle ear implants. Analysis of 101 ears and temporal bone experiments showed the umbo was feasible in 71% of cases and provided comparable sensor sensitivity and feedback to incudostapedial coupling. Spacer stiffness and contact force affected sensor sensitivity, with low pretension giving the most stable results. The findings support the umbo as a robust alternative coupling site for implantable middle ear sensors.
