  • Patent number: 10350764
    Abstract: A sensor assembly comprising first, second and third layers of flexible material forming, when superposed, a pressure-sensitive sensor having at least two sensor cells. The first layer comprises first and second electrically conductive regions mechanically connected to each other via an electrically non-conductive region. The second layer comprises a third electrically conductive region. The third electrically conductive region of the second layer overlaps the first and second electrically conductive regions of the first layer. The region of overlap defines an active region of a first and a second sensor cell. The third layer is formed of a conductive elastic material that cooperates under a local mechanical load in the active region with the first and second conductive regions of the first layer so that an electrical resistance between the electrical conductive regions changes in the place of the compressive load.

Interdigitated serpentine capacitors monitor strain in the back of the hand, while parallel plate capacitors monitor contact pressure on the palm. Thus the smart glove responds electrically to various types of hand motions. Thin film resistors responsive to changes in body temperature are also formed on the flexible substrate. Motion and temperature data is transmitted from the glove to a microprocessor via a passive RFID tag or an active wireless transmitter. An ASIC is embedded in the smart glove to relay real time sensor data to a remote processor.

A gap is provided between the switch poles, and the layer extends across the gap. The substrate can be a circuit board with electrical traces formed thereon to convey electrical current to the switch poles. As a sufficient force is applied to the surface of the layer of the variable resistance material, its resistance changes from a relatively high value, in which the switch is in a non-conducting state, to a relatively low value, in which the switch is in a conductive state. A protective sheet can optionally be included over the variable resistance layer and can include graphics/text to indicate the position of each switch in an array and its function.

  • Patent number: 8169295
    Abstract: A manually operable position sensor is shown, for providing control signals to an electronic device, such as an audio player. A fabric ribbon (101) has a length substantially longer than its width with insulating yarns and electrically conducting yarns included therein. The conducting yarns define three conductive tracks (103, 104, 105) running the length of the fabric. The conductive tracks are configured to interface with an electronic device at a first end. At a second end, an active region of the fabric forms part of a sensor assembly that is receptive to a manually applied pressure.

  • Patent number: 8018319
    Abstract: A foil-type switching element comprises a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer, which comprises one opening (18) defining an active area. An elongate resistive layer (20) is provided on the second carrier foil within the active area while elongate 5 shunt means (22) are arranged on the first miler foil within the active area and facing the resistive layer (20). The form of the opening (18) in the spacer is such that the active area generally tapers in the longitudinal direction of the elongate resistive layer (20), so that when pressure is applied on the switching element, the shunt means (22) shunt a portion of the resistive layer (20) that 10 progressively increases with pressure, from the broad end of the spacer opening (18) towards its narrow end.

  • Patent number: 7847674
    Abstract: A small inexpensive two terminal variable resistance assembly that conveniently changes its resistance when a force of an actuator is applied. It can be made for power applications as well as in miniature dimension versions in values from milli-ohms to meg-ohms. This variable resistor increases its power handling capacity during a decrease in its ohmic value, contrary to present three terminal potentiometers or reostats. It does this by a rolling action that increases or decreases two resistive surface areas in parallel. It could also be used as a variable capacitor.

  • Patent number: 7788799
    Abstract: A variable resistance device comprises a resistive member having a resistive resilient material. A first conductor is configured to be electrically coupled with the resistive member at a first contact location over a first contact area. A second conductor is configured to be electrically coupled with the resistance member at a second contact location over a second contact area. The first contact location and second contact location are spaced from one another by a distance. The resistance between the first conductor at the first contact location and the second conductor at the second contact location is equal to the sum of a straight resistance component and a parallel path resistance component. At least one of the first location, the second location, the first contact area, and the second contact area is changed to produce a change in resistance between the first conductor and the second conductor.

  • Patent number: 7772960
    Abstract: A force sensing resistor (FSR) includes a substrate having separated electrically conductive traces and another substrate having a resistive layer in which the substrates are subjected to a biasing force such that the substrates contact one another with the resistive layer electrically connecting the traces with a resistance inversely dependent on the biasing force. Upon an external force applied towards a substrate, the substrates contact one another with a total force which is the sum of the forces with the resistive layer electrically connecting the traces with a resistance inversely dependent on the total force. An FSR output which is a function of the resistance is measured. Whether a change in magnitude of the FSR output during a time interval is greater than a threshold is determined. A touch applied on the FSR is detected during the time interval if the change is greater than the threshold.
