马达加斯加巨猴(Daubentonia madagascar)是世界上最大的夜行灵长类动物,具有许多独特的适应性。aye-aye最显著的特征可能是它独特的近场听觉系统,用来支持它独特的轻拍扫描过程。这种轻拍扫描技术代表了动物生物听觉系统的显著进化创新。目前的研究为提出一种仿生方法提供了初步的见解,以确定不同的形态特征如何影响ayeaye的声学近场听觉系统。实验装置包括安装在Universal Robotics机械手(UR5)上的微型压电锤(集成系统提供受控的敲击过程)和预极化电容测量麦克风(用于捕获木制样品上每次敲击产生的声音)。利用从尸体上获得的CT扫描,3D打印了aye-aye的耳廓。结果表明,该仿生装置可以成功地用于评价眼-眼近场听觉系统。
The aye-aye (Daubentonia madagascariensis) is the largest nocturnal primate in the world and possesses a number of distinct adaptations. The most striking feature of the aye-aye is perhaps its exceptional near-field auditory system adopted to support its unique tap-scanning process. This tap-scanning technique represents prominent evolutionary innovations in the animal’s biological auditory system. The current study provides an initial insight into proposing a biomimetic approach to determine how different morphological features might impact the ayeaye’s acoustic near-field auditory system. The experimental setup comprised a miniature piezoelectric hammer mounted on a Universal Robotics manipulator (UR5) (the integrated system provides a controlled tapping process) and a prepolarized capacitive measurement microphone (to capture the acoustic sound coming from each tap on the wooden sample). The pinnae of the aye-aye were 3D printed using a CT scan obtained from a carcass. The results show that the biomimetic setup can successfully be used for evaluating the near-field auditory system of aye-ayes.
