Abstract
A force sensor includes at least one cavity defining at least two surfaces having different orientations. On each of said surfaces is disposed at least one respective detection structure sensitive to a pressure exerted on the corresponding surface. A resiliently deformable medium at least partially fills the cavity by coming into contact with the surfaces and defines a detection surface, on which a force to be detected is likely to be exerted. The application of this force is likely to generate stresses on each detection structure due to the transmission of forces by the medium.
Claims27
A force sensor comprising:
- at least one cavity defined by a hollow rigid support, the cavity defining at least two cavity surfaces having different orientations;
- on each of the cavity surfaces, at least one respective detection structure supported by the hollow rigid support and sensitive to a pressure exerted on a corresponding measurement surface of the detection structure;
- and
- a resiliently deformable medium at least partially filling the cavity by coming into contact with the measurement surfaces, and defining a detection surface configured to detect a force exerted thereon, the application of this force being likely to generate stresses on each detection structure as a result of the transmission of forces by the medium.
