在这项研究中，我们修改了我们以前开发的微触觉传感器（MTS），不仅测量弹性与高灵敏度，但也检测接触的瞬间。首先，使用有限元分析对MTS进行模态分析，以找到纵向和旋转振动模式存在的频率。其次，MTS振荡使用这两种类型的振动，其基本性能进行了评估。虽然主要纵向振动的谐振模式以压痕和弹性依赖的方式偏移，但是接触时旋转振动的消失导致用于发出触摸检测信号的谐振频率的突变。最后，利用改进的MTS，我们开发了触觉映射技术，并使用它来获得轮廓图像和地形杨氏模量信息的猪心切片冠状动脉。
In this study, we modified our previously developed Micro-Tactile Sensor (MTS) not only to measure elasticity with high sensitivity but also to detect the instant of contact. First, modal analysis of the MTS was undertaken using finite element analysis to find a frequency where longitudinal and rotational vibration modes exist. Second, the MTS oscillated using these two types of vibration, and its basic performance was assessed. While the resonance mode of major longitudinal vibration shifted in an indentation and elasticity dependent manner, a disappearance of the rotational vibration upon contact resulted in abrupt change in resonance frequency which was used to signal touch detection. Last, using the modified MTS, we developed Tactile Mapping technology and used it to obtain a contour image and topographical Young's modulus information for a slice of porcine heart with coronary artery.
