Abstract
A sensor comprising a whisker shaft and a follicle is provided. The shaft has a root end and a tip end and the shaft tapers from the root end to the tip end so that the root end is wider and the tip end is narrower. The root end is pivotably mounted in the follicle.
Claims19
A method of sensing comprising:
- providing one or more artificial whisker sensors mounted in a hub, the one or more artificial whisker sensors comprising a tapered whisker shaft;
- measuring the frequency spectrum of the vortex-induced vibration caused by interaction between the one or more artificial whisker sensors and a medium of interest.
A method of sensing comprising:
- providing one or more artificial whisker sensors, the one or more artificial whisker sensors comprising a tapered whisker shaft;
- moving the tapered whisker shaft through a medium of interest and in doing so causing vortex-induced vibration;
- and
- measuring the frequency spectrum of the vortex-induced vibration.
1 more element
A method of measuring surface compliance, comprising the steps of:
- providing one or more artificial whisker sensors mounted in a hub, the one or more artificial whisker sensors comprising a tapered whisker shaft;
- and
- using whisker deflection along with a known motion to measure compliance and/or hardness of a surface.
