Problems solved by technology

[0004] However, in the flexible circuit board disclosed in Patent Document 1, the resistance of the wiring portion fluctuates from the initial value due to repeated expansion and contraction of the insulating base material.
Therefore, for example, when the flexible circuit board of Patent Document 1 is applied to a motion sensor that detects the motion of a person, a robot, etc. based on a change in resistance value accompanying expansion and contraction of the wiring portion, the motion cannot be detected with high accuracy.

no. 1 Embodiment approach

[0041] figure 1 It is a plan view showing the sensor according to the first embodiment of the present invention. figure 2 is showing figure 1 A diagram of the wearing state of the sensor shown. image 3 It is a graph showing the relationship between the amount of elongation of the sensing wiring and the rate of change in resistance. Figure 4 is along figure 1 A cross-sectional view of line A-A in.

[0042] figure 1 The shown sensor 1 is a wearable terminal that can be used as a motion sensor worn on a movable body and used to detect the motion of the movable body. In addition, the movable body is not particularly limited, and examples thereof include various animals including humans, various robots having joints, and various moving bodies such as automobiles and airplanes. In addition, in this embodiment, for the convenience of description, as figure 2 As shown, a case where the movable body is a person H and the sensor 1 is arranged on the arm across the elbow joint...

no. 2 Embodiment approach

[0089] Figure 5 It is a plan view showing the sensor according to the second embodiment of the present invention.

[0090] The sensor of this embodiment is the same as that of the above-mentioned first embodiment except that the structure of the stretchable base 6 is different.

[0091] In addition, in the following description, regarding this embodiment, differences from the above-mentioned first embodiment will be mainly described, and description of the same items will be omitted. In addition, in Figure 5 In , the same reference numerals are assigned to the same structures as those in the above-mentioned embodiment.

[0092] Such as Figure 5 As shown, in the sensor 1 of the present embodiment, the stretchable base 6 has the reference wiring support portion 61 supporting the reference wiring 71 and the sensing wiring supporting portion 62 supporting the sensing wiring 72 . In addition, the sensing wiring support portion 62 has a first sensing wiring supporting portion...

no. 3 Embodiment approach

[0095] Image 6 It is a plan view showing the sensor of the third embodiment of the present invention.

[0096] The sensor of this embodiment is the same as the above-mentioned first embodiment except that the second base is omitted and the structure of the wiring 7 is different.

[0097] In addition, in the following description, regarding this embodiment, differences from the above-mentioned first embodiment will be mainly described, and description of the same items will be omitted. In addition, in Image 6 In , the same reference numerals are assigned to the same structures as those in the above-mentioned embodiment.

Abstract

Provided is a sensor which includes a stretchable substrate having a stretching property, and wires provided to the stretchable substrate. The wires include a first wire, and a second wire larger in resistance value variation due to extension of the stretchable substrate than the first wire. Further, the sensor includes a detection section adapted to correct a resistance value of the second wire in accordance with a resistance value of the first wire, and detect the extension of the stretchable substrate based on the resistance value of the second wire which has been corrected. Further, the detection section detects deterioration of wires in accordance with the resistance value of the first wire.

Description

technical field [0001] The present invention relates to sensors. Background technique [0002] For example, Patent Document 1 discloses a flexible circuit board including: a stretchable circuit body provided with a stretchable wiring portion on a stretchable insulating base material; and a non-stretchable component mounting substrate. , which is stacked on a predetermined area of ​​the stretchable circuit body. According to such a configuration, the wiring can be expanded and contracted, and can be suitably used in movable parts such as robots. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-145842 [0004] However, in the flexible circuit board disclosed in Patent Document 1, since the insulating base material repeatedly expands and contracts, the resistance of the wiring portion fluctuates from the initial value. Therefore, for example, when the flexible circuit board of Patent Document 1 is applied to a motion sensor that detects the motion of a person, ...
