    Abstract: In one general aspect, an apparatus comprises a material including a non-layered mixture of an polymeric foam with a plurality of voids; and a plurality of conductive fillers disposed in the polymeric foam. The apparatus may produce an electrical response to deformation and, thus, function as a strain gauge. The electrical response may be a decrease in electrical resistance. The electrical response may be an electric potential generated. The conductive fillers may include conductive nanoparticles and/or conductive stabilizers. In another general aspect, a method of measuring compression strain includes detecting, along a first axis, an electrical response generated in response to an impact to a uniform composite material that includes conductive fillers and voids disposed throughout an elastomeric polymer, and determining a deformation of the impact based on the electrical response. The impact may be along a second axis different from the first axis.

    Abstract: This surface potential sensor is provided with an electret electrode (28), which is configured of a metal film (26) and an electret film (27), said electret electrode being provided on an upper surface of a diaphragm (25) of a semiconductor substrate. Four piezoresistors (29a, 29b, 29c, 29d) are formed on the diaphragm (25), and a distortion quantity detecting unit (32) is configured by forming a bridge circuit using the piezoresistors. Since an electrostatic force that operates between an object and the electret electrode (28) changes corresponding to potential of the object, and the electret electrode (28) warps corresponding to the change, the potential of the object can be detected by measuring a distortion quantity of the electret electrode (28) by means of the distortion quantity detecting unit (32). Consequently, not only the potential of the object but also a polarity thereof can be detected with reduced size and high sensitivity.

  • Patent number: 9605993
    Abstract: A load cell (1) has a deformable body with upper and lower contact surfaces (3, 4), through which a force is introduced. Support points (5) of the contact surfaces define a line of action (6) of the force. At least one column-shaped portion (7) of the deformable body has a central longitudinal axis (8) and a circumferential surface whose generating line runs parallel to the central longitudinal axis (8). A first determining means (9) installed on the column-shaped portion converts a mechanical deformation into an electronic signal, and a second determining means (10) installed on the column-shaped portion converts a deviation of the central longitudinal axis (8) from the line of action (6) into a representative signal. Each determining means has at least one strain gauge.

  • Patent number: 9523616
    Abstract: An apparatus, and an associated method, forms a user interface permitting input of input instructions to an electronic device. Input commands are evidence by tactile input forces applied to a force receiving surface. Force sensing elements are positioned to sense indications of the tactile input force. The force sensing element is caused to exhibit a selected input parameter value through application of a selected force thereto by application of a tightening torque to a fastener positioned in proximity to the force sensing element.

  • Patent number: 9429485
    Abstract: A bolt shear force sensor for in-service monitoring is provided in which the sensor includes a deformable ring with channel-like cross-sections and a wire egress hole. The ring surrounds a bolt or fastener to be tested. The channel-like cross sections face exterior to a center of the ring. Strain sensing elements are mounted within the channel cross-sections as an outer circumference of the ring. The sensing elements capture hoop strain from surrounding plates of the operating system which holds the fastener. A signal conditioner operationally connected via wire conductors is used to convert strain sensing signals from the sensing elements to strain output. The strain outputs are then used in conjunction with a calibration curve of shear force versus strain to determine the magnitudes and directions of the resultant shear forces.

  • Patent number: 9416648
    Abstract: A technique facilitates measuring loads while compensating for the effects of differential pressure. The technique utilizes a load cell comprising a chassis and a sensing element mounted on the chassis. A housing encloses the sensing element in a chamber formed between the chassis and the housing. The housing is connected to the chassis in a manner to transfer loading, e.g. compressive, tensile, and/or torque loading. A pressure compensating piston is positioned within an interior of the chassis and the housing. A plurality of seal points is located in a manner which isolates the sensing element from the effects of differential pressures between the interior and an exterior of the load cell.
