The ability to characterize tactile perception will be crucial to the effective use of tactile information in the next generation of information communication technology. Tactile perception depends on multiple properties of the surface being touched, including surface texture, stiffness, and temperature. To quantitatively evaluate the contribution of each individual property to tactile perception, our research group has used microfabricated tactile samples that have identical properties except for the one property under study. Until now, a separate sample has been needed for each level of each property of interest since the samples have lacked the capacity to vary property levels. In this research, we propose tactile samples that can change surface texture simply by being stretched. The proposed samples are made of PDMS and have grooves perpendicular to their length. In the initial state, the grooves are barely perceptible; however, when the sample is stretched lengthwise, the g...

具有可变表面纹理的触觉样品以研究触觉感知特性

表征触觉感知的能力对于下一代信息通信技术中有效使用触觉信息至关重要。触觉取决于要触摸的表面的多个属性，包括表面纹理，刚度和温度。为了定量评估每个属性对触觉感知的贡献，我们的研究小组使用了微制造的触觉样品，这些样品除了所研究的一个属性外，具有相同的属性。到现在为止，由于每个样本的属性都缺乏改变属性级别的能力，因此对于每个感兴趣的属性的每个级别都需要一个单独的样本。在这项研究中，我们提出了一种可以通过简单拉伸就可以改变表面纹理的触觉样品。建议的样品由PDMS制成，并具有垂直于其长度的凹槽。在初始状态下，几乎看不到凹槽。但是，当样品纵向拉伸时，g ...
