摘要： The present strain gauge includes a substrate having flexibility; a resistor formed from a material containing at least one of chromium and nickel, on the substrate; a pair of wiring patterns formed on the substrate and electrically connected to both ends of the resistor; and a pair of electrodes formed on the substrate and electrically connected to the pair of wiring patterns, respectively. The wiring patterns include a first layer extending from the resistor, and a second layer having a lower resistance than the first layer and layered on the first layer. On the substrate, an electronic component mounting area is demarcated, on which an electronic component electrically connected to the electrodes is mounted.

摘要： A strain gauge includes a flexible substrate and a functional layer formed of a metal, an alloy, or a metal compound, directly on one surface of the substrate. The strain gauge includes a resistor formed of a film including Cr, CrN, and Cr2N, on one surface of the functional layer. The substrate has an expansion coefficient in a range of from 7 ppm/K to 20 ppm/K.

摘要： A strain gauge includes a strain detecting unit and a temperature detecting unit that are formed on or above a flexible substrate. The strain detecting unit includes a resistor formed as a film containing Cr, CrN, and Cr2N, on one surface of a functional layer. A first metallic layer formed of a material of which a gauge factor is less than that of the resistor is laminated on a folded portion, and a resistance value of the first metallic layer on the folded portion is less than a resistance value of the folded portion. The temperature detecting unit is a thermocouple including a second metallic layer formed of a same material as the resistor, on or above the substrate; and a third metallic layer formed of a same material as the first metallic layer, on the second metallic layer.

摘要： A strain gauge includes a flexible substrate, resistors each formed of a film that includes Cr, CrN, and Cr2N, and a functional layer formed of a metal, an alloy, or a metal compound, the functional layer being in a lower surface of the resistors. The resistors include a first resistor formed on or above a predetermined surface of the substrate; a second resistor of which a grid direction faces a different direction from the first resistor, the second resistor formed on or above the predetermined surface of the substrate or a surface parallel to the predetermined surface; and a third resistor formed on or above a surface adjacent to the predetermined surface of the substrate.

摘要： A slip sensor includes a first insulating layer, a second insulating layer, and a member configured to elastically deform in accordance with a force. A difference between a resistance value set between a given pair of electrodes associated with a given first resistive portion and a resistance value set between a given pair of electrodes associated with a given second resistive portion facing the given first resistive portion continuously varies in accordance with elastic deformation of the member that is caused by a shear force.

摘要： A posture adjusting device includes a support member with a pressure receiving surface to be pressed by a body of a user, multiple posture adjusting members each configured to change an uneven state of the pressure receiving surface, a sensor configured to output, when a given posture adjusting member is pressed by the body via the pressure receiving surface, a resistance value that constantly varies in accordance with a magnitude of a press force that is transferred via the given posture adjusting member, a drive unit configured to independently drive each of the multiple posture adjusting members, and a control unit configured to identify the pressed posture adjusting member based on the output of the sensor, and to control the drive unit to cause the pressed posture adjusting member to be moved or deformed to thereby cause the uneven state of the pressure receiving surface to change.
