Abstract: A stretchable device includes strain gauges and electrical wiring. Each strain gauge includes a first strain gauge and a second strain gauge. The first strain gauge and the second strain gauge are coupled to each other. The electrical wiring includes a first potential line, a second potential line, a coupling line coupling the first potential line to the second potential line, a first signal line, and a second signal line. The first signal line detects a third potential at a first coupling point. The second signal line detects a fourth potential at a midpoint of the coupling line. One of the first strain gauge and the second strain gauge is an inner peripheral strain gauge. The other thereof is an outer peripheral strain gauge. The amount of change in resistance of each strain gauge is detected based on a potential difference between the third potential and the fourth potential.

Abstract: A stretchable device includes a resin base member, a signal line, and a strain gauge. The resin base member includes: bodies disposed separately from each other; and hinges that couple the bodies while meandering. Each hinge includes: a base and bends. The bends include a first bend coupled to the base. The first bend includes a first inner peripheral portion and a first outer peripheral portion with respect to a center in a width direction orthogonal to a length direction in which the hinge extends. The base includes an inner peripheral coupling portion coupled to the first inner peripheral portion and an outer peripheral coupling portion coupled to the first outer peripheral portion with respect to the center in the width direction. The signal line is provided to the hinge. An imaginary center line passing through the center of the signal line overlaps the outer peripheral coupling portion.

Abstract: According to one embodiment, an electronic device includes a first substrate, a second substrate opposing the first substrate, a pressure sensitive layer disposed between the first substrate and the second substrate, and an elastic member that covers the first substrate, the second substrate and the pressure sensitive layer. The first and second substrates include a first and second insulating substrates formed into a mesh-like shape. The elastic member includes slits that are formed around a first island-shaped portion of the first insulating substrate and a second island-shaped portion of the second insulating substrate. The slits open when the elastic member is expanded.
