基于生物启发的搅拌动作的新一代传感器将有助于确定固体物体和流体涡流的存在和位置，类似于老鼠和海豹等带有胡须的动物所使用的机制。通过使用纳米压痕，我们证明了横截面的机械性能基本上是均匀的，但从晶须底部（3.9 GPa 弹性模量）到尖端（3.1 GPa 弹性模量）纵向变化。最近的几项研究表明，高频信息通过晶须传播，晶须根据其物理特性进行调整。为了充分理解和模拟这些特性，这项研究展示了比之前假设的更复杂的晶须结构。
A new generation of sensors based on biologically inspired whisking action will help determine the presence and location of solid objects and fluid vortices similar to mechanisms used by whisker bearing animals such as rats and seals. By using nanoindentation, we demonstrate that mechanical properties are essentially uniform by cross section, but vary longitudinally from the whisker base (a 3.9 GPa elastic modulus) to the tip (a 3.1 GPa elastic modulus). Several recent studies show propagation of high frequency information through whiskers that are tuned by their physical properties. In order to fully understand and model these properties, this study demonstrates a more complex whisker structure than previously assumed.
