摘要： A strain gauge includes a flexible substrate; and resistors each formed of a Cr composite film. The resistors include a first resistor and a second resistor that are formed on one side of the substrate, and include a third resistor and a fourth resistor that are formed on another side of the substrate. The first resistor, the second resistor, the third resistor, and the fourth resistor constitute a Wheatstone bridge circuit.

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.

摘要： A tactile sensor includes a support member with a curved surface, a sensor body disposed on the support member, and a buffer member with which the sensor body is coated, the buffer member being configured to, in response to contacting an object, transfer a force applied from the object to the sensor body. The sensor body includes an insulating layer, multiple first resistive portions of which a longitudinal direction is directed to a first direction of each and that are juxtaposed on one side of the insulating layer, multiple second resistive portions of which a longitudinal direction of each is directed to a second direction intersecting with the first direction and that are juxtaposed on another side of the insulating layer, and a pair of electrodes provided at both end portions of each of the first resistive portions and the second resistive portions. The press force applied from the object is transferred to the sensor body, and at least one given resistive portion among the first resistive portions and the second resistive portions is pressed, so that a resistance value between a given pair of electrodes associated with the pressed at least one given resistive portion among the first resistive portions and the second resistive portions constantly varies in accordance with a magnitude of the press force.

摘要： A strain gauge includes a flexible substrate, and a resistor formed of material containing at least one from among chromium and nickel, on or above the substrate. The resistor includes a first layer that is a lowermost layer; and a second layer that is a surface layer laminated on or above the first layer. The second layer is a layer having a higher density than the first layer. The first layer has a first surface provided on a side where the flexible resin substrate is situated, the functional layer being laminated on the first surface. The first layer has a second surface on which the second layer is laminated.
