The invention relates to a guidewire system, a measuring system, and a method for manufacturing such guidewire system. The guidewire system comprises a guidewire and a surface acoustic wave sensor device. A portion of a surface of the guidewire is coated by the surface acoustic wave sensor device. The surface acoustic wave sensor device may be configured for measuring a pressure change. The surface acoustic wave sensor device comprises a piezoelectric substrate and a transducer. A thickness of the surface acoustic wave sensor device perpendicular to a longitudinal direction of the guidewire is smaller than 100 µm.
