A method of fabricating electrically conductive synthetic vocal fold replicas and monitoring their vibration via resistance measurement is presented. Normally non-conductive silicone replicas were coated with conductive graphite and subjected to long-term vibration tests. Synchronized resistance and imaging data using hemilarynx and full larynx configurations showed an inverse correlation between replica contact area and resistance during vibration, similar to clinical electroglottography (EGG) used to estimate vocal fold contact area. This method has potential for long-term replica vibration monitoring and studying basic physical relationships between resistance and contact area in vocal folds and vocal fold replicas.
本文提出了一种制造导电合成声带复制品并通过电阻测量监测其振动的方法。通常不导电的硅胶复制品被涂上导电石墨，并进行长期振动测试。使用半喉和全喉配置的同步电阻和成像数据显示，复制品在振动过程中的接触面积与电阻呈负相关，类似于用于估计声带接触面积的临床电子声门图（EGG）。该方法具有长期监测复制品振动以及研究声带和声带复制品中电阻与接触面积之间基本物理关系的潜力。
