  • Artificial lateral line
    Publication number: 20080072682
    Abstract: An artificial sensor comprises at least one substrate, and a plurality of flow sensors disposed on the at least one substrate for providing a plurality of spatial-temporally varying signals representing a hydrodynamic stimulus. The plurality of flow sensors are spatially distributed on the at least one substrate. A processor is coupled to the plurality of flow sensors for receiving the signals and determining spatial-temporal information from the received signals.

  • Microfabricated pressure and shear stress sensors
    Publication number: 20080022778
    Abstract: A microfabricated pressure sensor. The pressure sensor comprises a raised diaphragm disposed on a substrate. The diaphragm is configured to bend in response to an applied pressure difference. A strain gauge of a conductive material is coupled to a surface of the raised diaphragm and to at least one of the substrate and a piece rigidly connected to the substrate.

  • Method of fabricating an artificial haircell
    Publication number: 20080022513
    Abstract: Method of fabricating an artificial haircell. A cilium, a strain gauge connected to the cilium, and a ductile hinge are microfabricated on a substrate by surface micromachining. The cilium and the strain gauge are raised with respect to the substrate by application of a magnetic field, thus bending the hinge.
