Abstract: Systems, methods, and apparatus to provide artificial whisker filaments are disclosed and described. An example artificial whisker is tapered to include a tip diameter smaller than a base diameter of the artificial whisker, the artificial whisker formed from a polymer arranged to permit elastic deformation of the artificial whisker, the deformation of the artificial whisker to transmit force to a sensor associated with a base of the artificial whisker. An example method of manufacturing an artificial whisker includes removably affixing a first end of a filament to a heated, non-stick surface; drawing the filament across the surface to form a first, tapered portion, a second portion of the filament remaining on the surface, wherein the filament is to be drawn until the first portion is disengaged from the surface; and separating the first, tapered portion of the filament from the second portion of the filament to form a tapered artificial whisker.

Abstract: An elastically deformable load bearing structure includes a measuring arrangement for measuring a magnitude of a load acting on the load bearing structure in a loadable section. A mechanical transmission element extends from the loadable section to a measuring section of the load bearing structure and cooperates operatively with a sensor. The sensor is arranged in the measurement section. The mechanical transmission element is constructed as a pivotable rocker supported by a rocker bearing positioned inside a length of the transmission element.

Abstract: A variable resistance conductive rubber sensor and method of detecting an object/human touch therewith is provided. The sensor has a sensor body constructed from electrically conductive rubber. The sensor body extends between opposite first and second ends. A first wire is operably connected to the first end and a second wire may be operably connected to the second end, with the first and second wires being brought into electrical communication with one another by the intermediately extending electrically conductive rubber of the sensor body. A microcontroller is operably connected to the sensor body to detect the presence of an applied force or human touch on the sensor body.

Abstract: Provided is a pressure sensing element configured to be flexible, and capable of demonstrating a stable electrical reliability over a long period; and, a pressure sensor having such pressure sensing element. A pressure sensing element (100) has an electro-conductive pressure sensing film (14), a sensor electrode (12) provided at a position faced to the pressure sensing film (14), and an insulating layer (13) which creates a predetermined distance “A” between the pressure sensing film (14) and the sensor electrode (12) so as to keep them apart from each other, the pressure sensing film (14) being a resin film containing carbon particles (140); and, a pressure sensor (200) has the pressure sensing element (100), and a detection unit (210) which is electrically connected with the pressure sensing element (100) so as to detect contact resistance between the pressure sensing film (14) and the sensor electrode (12).

Abstract: A force sensing element is used in a pressure transducer. The force sensing element includes a flat, disc-type spring having a unitary body that circumscribes a central axis, and a plurality of spirals that are continuous with each other and extend radially outwardly from the central axis. The plurality of spirals includes nested symmetrical flights having walls with a non-uniform thickness, and the disc spring is uniformly deflectable along the central axis in response to force acting on the disc-type spring. The spring is configured to have a high accuracy and a high fatigue life such that the spring is suitable for use in high-pressure applications that may require repeatability while operating with over 10 million cycles of unidirectional or bi-directional axial loading.

Abstract: A force sensor device for determination of a measurement value of a force and generation of an electrical signal based on the measurement value includes a force ring with a force application surface and a support surface for support of a circuit board, on which passive and active electronic components are arranged. The circuit board is mechanically or adhesively fixated on the support surface. At least one force transducer is electrically connected with the circuit board, and arranged and configured at the force ring in such a way that deformations of the force ring, as a result of an axial force applied on the force ring, are measured. A housing lid is connected with the force ring, so that the force ring and the housing lid enclose the circuit board and the force transducer. Also provided is an external connection for picking up an electrical signal.

Abstract: There is disclosed a method for calibrating a measurement device, in which a probe is coupled with a base part by a flexure. The method includes setting a position of a probe of the measurement device by moving the base part so that a tip of the probe does not touch an object; obtaining information of a location of the probe representing a free weight of the probe; and moving the base part so that the tip of the probe moves towards a surface of the object and obtaining information of the location of the probe until the information indicates that the location of the tip of the probe has changed. There is also disclosed a measurement device including a base part; a probe having a tip; a flexure coupling the base part with the probe; means for moving the base part; and means for obtaining information of a location of the probe without contacting the flexure and/or the probe.

Abstract: A directional force sensor and sensing system are described. The directional force sensor includes a leaf spring and one or more load sensors disposed about the leaf spring such that in response to a force applied to the leaf spring, the one or more load sensors provide a signal. A controller is coupled to receive signals from the one or more directional force sensors and determines characteristics of forces applied to the directional force sensors.
