Abstract
The invention concerns a device for measuring the pressure of a fluid carried in a conduit. The device comprises a first electrode, a second electrode, a nanoassembly of conductive or semi-conductive nanoparticles in contact with the two electrodes, and a measurement device. The measurement device provides proportional information with respect to an electrical property of the nanoassembly. The electrical property is measured between the first and second electrode, and the electrical property is sensitive to the distance between the nanoparticles of the nanoassembly. The nanoassembly is mechanically linked to a flexible substrate having a mechanical linkage with the fluid carried in the conduit such that the distances between the nanoparticles of the nanoassembly are modified by a pressure variation in the fluid.
