  • Patent number: 9038483
    Abstract: Wireless strain and displacement sensors wirelessly monitor structural health and integrity, and are made by printing inductor-interdigital capacitor sensing circuits on a variety of substrates, including ceramic substrates, with thermally processable conductive inks. Sensors of the invention can be employed to detect strain and displacement of civil structures, such as bridges and buildings. The sensors include sensing elements that are mounted or printed on stiff, inflexible substrates, which prevent the sensing elements from bending, stretching, or otherwise warping when the sensor is strained. An interlayer between the sensing elements allows the sensing elements to move with respect to each other during application of strain. Thus, strain causes the sensing elements to move but not to deform, causing changes in sensor resonance that can be detected through wireless radio-frequency interrogation.

  • Patent number: 8997588
    Abstract: A flexible force or pressure sensing mat includes a first sheet of electrically conductive first paths, a second sheet of electrically conductive second paths, and a sensing layer positioned between the first and second sheets. The first and second conductive paths are oriented transversely to each other, and the locations of their intersections define individual sensing areas or sensors. The sensing layer is made from materials that have first and second electrical characteristics—such as capacitance and resistance—that vary in response to physical forces exerted thereon. A controller repetitively measures the multiple electrical characteristics of each sensor in order to produce a near real time pressure distribution map of the forces sensed by the mat. The mat can be used on a patient support surface—such as a bed, cot, stretcher, recliner, operating table, etc.—to monitor and help reduce the likelihood of a patient developing pressure ulcers.

  • Patent number: 8966996
    Abstract: With the Z-axis given as a central axis, on an XY-plane, arranged are a rigid force receiving ring, a flexible detection ring inside thereof, and a cylindrical fixed assistant body further inside thereof. Two fixing points on the detection ring are fixed to a supporting substrate, and two exertion points are connected to the force receiving ring via connection members. When force and moment are exerted on the force receiving ring, with the supporting substrate fixed, the detection ring undergoes elastic deformation. Capacitance elements or others are used to measure distances between measurement points and the fixed assistant body and distances between the measurement points and the supporting substrate. Elastic deformation of the detection ring is recognized for mode and magnitude, thereby detecting a direction and magnitude of force or moment which is exerted.

  • Patent number: 8966997
    Abstract: A pressure sensing sheet includes at least first, second, and third layers wherein the first and third layers each have conductive paths defined therein that are separated by nonconductive spacers. The orientation of the conductive paths of the first layer are transverse to the orientation of the conductive paths of the third layer. The second layer is made of material that has an electrical characteristic that changes with applied pressure, such as, but not limited to, piezoresistive or piezoelectric material. The first and/or third layers are made from multi-material sheets wherein a first type of material will repel conductive particles when subjected to an autocatalytic coating process, while the second type of material will bond with the conductive particles during the autocatalytic coating process. The use of different materials in the first and/or third layers facilitates the manufacturing of the conductive paths and nonconductive spacers.
