ABSTRACT:
A pressure sensor includes a pressure sensitive element for sensing a distributed fluid pressure and producing a signal in response. The pressure sensitive element is configured to be mountable on an airfoil or a hydrofoil, for example as a thin film piezoelectric element. The sensor finds applications, for example, in measuring lift or drag on the airfoil or hydrofoil.
