本文建立了一个仿生舌-腭系统，用于研究人在口腔中对纹理的感知。模型舌头由柔软的弹性体制成，其纤维状结构类似于人类丝状乳头。腭由平行于舌平面的刚性平板表示。为了探测生理流动条件下的行为，使用一种新的荧光成像技术，使亚微米分辨率的位移测量模型乳头的偏转。在稳定剪切流下使用光学透明的牛顿液体，我们表明乳头的变形允许其粘度从1 Pa s下降到水的粘度（1 mPa s），与先前提出的模型完全定量一致（Lauga等人，2016 Front. Phys.4，35（doi：10.3389/fphy.2016.00035））。该技术进一步验证了剪切稀化和光学不透明的乳制品系统。
An experimental biomimetic tongue–palate system has been developed to probe human in-mouth texture perception. Model tongues are made from soft elastomers patterned with fibrillar structures analogous to human filiform papillae. The palate is represented by a rigid flat plate parallel to the plane of the tongue. To probe the behaviour under physiological flow conditions, deflections of model papillae are measured using a novel fluorescent imaging technique enabling sub-micrometre resolution of the displacements. Using optically transparent Newtonian liquids under steady shear flow, we show that deformations of the papillae allow their viscosity to be determined from 1 Pa s down to the viscosity of water (1 mPa s), in full quantitative agreement with a previously proposed model (Lauga et al. 2016 Front. Phys. 4, 35 (doi:10.3389/fphy.2016.00035)). The technique is further validated for a shear-thinning and optically opaque dairy system.
