Abstract
A vascular graft includes a flexible substrate that can assume an unrolled configuration, in which the substrate extends along a main extension plane, and a rolled-up configuration, in which a first side of the substrate is facing radially inward and a second side of the substrate is facing radially outward. At least one pressure sensing device is arranged on the first side of the substrate and includes a first electrode, a second electrode, and a piezoelectric element arranged between the two electrodes. At least one velocity sensing device is arranged on the first side of the substrate and a first electrode, a second electrode, and a piezoelectric element arranged between the electrodes. The graft can be used in a vascular graft system.
