Title:
LIFT/DRAG PIEZOELECTRIC CONVERSION DEVICE AND FLOW SENSOR USING THE SAME
Document Type and Number:
Japanese Patent JP2020134433
Kind Code:
A
Abstract:
To provide a lift/drag piezoelectric conversion device which reduces a cross-sectional area on the vertical plane with respect to flow of the detected fluid and suppresses turbulence and pressure loss of the fluid, and to provide a flow sensor using the same.SOLUTION: A lift/drag piezoelectric conversion device includes: an airfoil part which generates the lift relative to the flow of the detected fluid; and a piezoelectric cantilever which has a piezoelectric member on one surface and/or another surface. The airfoil part is connected to one end of the piezoelectric cantilever so that the longitudinal direction of the piezoelectric cantilever and a front edge of the airfoil part are substantially perpendicular. The other end of the piezoelectric cantilever is fixed at a support part, the mounting surface of the piezoelectric member is substantially parallel to the flow of the detected fluid, and the airfoil part has a bent part starting from an original rear edge with respect to an original chord line.SELECTED DRAWING: Figure 3
