提出了一种基于鳍状触须的新型水下传感器的设计方法。近年来，不同的研究小组已经研究了鳍足动物（海豹，海狮等）如何使用它们的胡须来跟踪潜在猎物留下的水动力痕迹。大部分注意力都集中在密封须的特殊几何形状上，这种形状似乎可以抑制涡激振动，并被怀疑可以提高传感能力。在这项研究中，我们的小组着眼于流体激励信号的机械转导的晶须状传感器和晶须的机械结构在传感过程中的作用。我们将晶须结构定义为晶须轴加上安装晶须的毛囊状基部，该基部使得能够测量由流体相互作用激发的信号。讨论了一种基于目标流体信号的设计方法，并描述了一个原型。传感性能的特点是使用冯卡门尾流。
In this paper we present the design and the design methodology for a new type of underwater sensor based on pinniped whiskers. In recent years various groups have looked into how pinnipeds (seals, sealions, etc) use their whiskers to track hydrodynamic trails left by potential prey. Most of the attention has been directed to the particular geometry of seal whiskers which seems to suppress vortex-induced vibrations and is suspected to improve sensing capabilities. In this study our group looks at the mechanical transduction of fluid-excited signals by whisker-like sensors and the role of the whisker mechanical structure in the sensing process. We define the whisker structure as the whisker shaft plus the follicle-like base where the whisker is mounted and that enables the measurements of signals excited by fluid interactions. A design approach based on target fluid signals is discussed and a prototype is described. Sensing performance is characterized using von-karman wakes.
