Abstract

In this study, a method for determining the optimal location and orientation of an implantable piezoelectric accelerometer on the short process of the incus is presented. The accelerometer is intended to be used as a replacement for an external microphone to enable totally implantable auditory prostheses. The optimal orientation of the sensor and the best attachment point are determined based on two criteria-maximum pressure sensitivity sum and minimum loudness level sum. The best location is determined to be near the incudomalleolar joint. We find that the angular orientation of the sensor is critical and provide guidelines on that orientation. The method described in this paper can be used to further optimize the design and performance of the accelerometer.

摘要

在本研究中，提出了一种确定可植入式压电加速度计在砧骨短突上的最佳位置和方向的方法。该加速度计旨在用作外部麦克风的替代品，以实现完全可植入的听觉假体。基于两个标准——最大压力灵敏度总和和最小响度水平总和，确定了传感器的最佳方向和最佳附着点。确定最佳位置在砧镫关节附近。我们发现传感器的角度方向至关重要，并提供了关于该方向的指导方针。本文所述方法可用于进一步优化加速度计的设计和性能。
