摘要： 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.

摘要： A pressure sensor has a polygonal cylindrical stem having a bottom wall and a plurality of side walls including a remarked side wall, a diaphragm constituted by a portion of the remarked side wall, and a sensing element attached to the remarked side wall. Each of the side walls extends along a longitudinal direction of the stem so as to face a hollow of the stem. A center axis of the hollow along the longitudinal direction is shifted from a center axis of the stem toward the remarked side wall so as to differentiate a thickness of the remarked side wall from those of the other side walls. The diaphragm is deformable in response to a pressure of a medium introduced in the hollow. The sensing element senses a deformation of the diaphragm and outputs a sensing signal indicating the deformation of the diaphragm.

摘要： A metal piece is provided with a body portion having a center passageway extending from one end thereof to a point short of the opposite end thereof, such body portion having two flat parallel sides lying parallel to the center axis of the passageway. A pair of resistance strain gages are bonded to each of the two flat sides above the passageway. One strain gage on each flat side is oriented to measure transverse strain and the other is oriented to measure axial strain. The four strain gages are connected to form a Wheatstone bridge, the transverse strain gages causing the bridge to provide an indication of fluid pressure within the passageway and the axial strain gages providing temperature compensation for the bridge.

摘要： Disclosed is a pressure determining unit configured for determining a pressure of a fluid. The pressure determining unit comprises a body structure and a deformation detector. The body structure has a fluidic path configured for conducting the fluid, wherein the body structure has a first surface in a first dimension and in a second dimension, and a thickness in a third dimension. The deformation detector is configured for responding to an elongation into the second dimension of the first surface of the body structure by generating a signal indicative of a value of the pressure of the fluid in the body structure. The fluidic path of the body structure comprises one or more first channel segments, each first channel segment having a height into the third dimension being at least twice of its width into the second dimension.

摘要： Techniques are described herein that perform pressure sensing using pressure sensor(s) that include deformable pressure vessel(s). A pressure vessel is an object that has a cross section that defines a void. A deformable pressure vessel is a pressure vessel that has at least one curved portion that is configured to structurally deform (e.g., bend, shear, elongate, etc.) based on a pressure difference between a cavity pressure in a cavity in which at least a portion of the pressure vessel is suspended and a vessel pressure in the pressure vessel.
