Research Description

Fabrication of a Direct Shear Flow Sensor Using Long, Vertically Aligned Barium Titanate Nanowires

Nanowires have unique properties due to their high surface area to volume ratio, and large aspect ratio. Barium titanate is a piezoelectric material which can be synthesized in nanowire form. A shear stress sensor is fabricated using these nanowires and characterized in an electromagnetic shaker. Novel fabrication techniques are tested to determine ideal configuration for measuring shear stress. An acoustic plane wave tube will be used to further characterize devices in a fluid medium. Eventually, these shear stress sensors may be used to measure blood flow.
