  • Patent number: 10871867
    Abstract: A capacitive MEMS force sensor for touch recognition and force measurement in touch screens is provided. The sensor includes two planar conductive electrodes separated by a predetermined distance using an elastic spacer to define an initial capacitance value of the sensor. An applied external force deforms the elastic spacer and minimizes the gap between sensor electrodes to alter the nominal capacitance value. This change in capacitance is monitored to measure the magnitude of the touch force. The sensor includes two types of the elastic spacers with different values of stiffness to overcome the trade-off between sensitivity and dynamic range of force measurement. These elastic spacers are interposed between sensor electrodes and are offset with a height difference to provide two ranges of force measurement.

    Abstract: A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having several piezoelectric regions within a piezoelectric material layer that may generate a voltage when deformed in a localized area.

The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen and detect multiple touch locations.

  • Patent number: 9200972
    Abstract: An external force judgment method including a reference value acquisition step of acquiring a reference value of a relative position or angle of a second member with respect to a first member when a robot on which no external force is acting or on which a known external force is acting is assumed to be operated by a predetermined command in advance; a measured value acquisition step of acquiring a measured value of a relative position or angle of the second member with respect to the first member when the robot is operated by the predetermined command; and a judgment step of judging the presence or absence of an external force acting on the robot based on a difference between the reference value and the measured value and a predetermined threshold value.

  • Patent number: 9121782
    Abstract: A first substrate that includes pressure sensors which are disposed in plural around a reference point; an approximately hemispherical elastic protrusion that is positioned so that the center of the elastic protrusion is approximately disposed in a position which is overlapped with the reference point, and is elastically deformed by an external force; and a second substrate that is separated from the elastic protrusion and installed on a side which is opposite to the first substrate are provided. When the external force is applied, a predetermined calculation is performed by using a pressure value which is detected through each pressure sensor, and the direction and the intensity of the applied external force are obtained.

  • 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: 9038482
    Abstract: A kiosk apparatus that may select for a person a recommended footcare product based on pressure measurements collected from pressures sensors or calculated biomechanical data estimates. Pressure measurements and calculated biomechanical data estimates may be used to determine if a foot is unshod on the pressure sensor and also group a person into a classified subgroup. The pressure measurement and calculated biomechanical data estimates may also be used to select a recommended footcare product.

  • 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.
