Abstract: According to an aspect, a stretchable device includes: a stretchable substrate comprising bodies and hinges that couple the bodies to each other; and a pair of stretchable resins with the stretchable substrate interposed therebetween. The stretchable device includes a detection region in which a load is capable of being detected and a non-detection region when viewed in a stacking direction in which the stretchable substrate and the stretchable resins overlap. One or more of the hinges are detection hinges each provided with a strain gauge. All of the detection hinges overlap the detection region when viewed in the stacking direction. The stretchable resins each includes: a bonded region that overlaps the non-detection region when viewed in the stacking direction and is bonded to the stretchable substrate; and an unbonded region that overlaps the detection region when viewed in the stacking direction and is not bonded to the stretchable substrate.

Abstract: According to an aspect, a stretchable device includes: a resin base member; and an array layer stacked on the resin base member. The resin base member includes: bodies separated from each other; and hinges that couple the bodies. Each hinge includes bends. Each bend is divided into an inner peripheral portion positioned on an inner side and an outer peripheral portion positioned on an outer side with respect to a center serving as a boundary in a width direction intersecting a direction in which the bend extends. The inner peripheral portions included in one of the hinges constitute an inner peripheral region. The outer peripheral portions included in one of the hinges constitute an outer peripheral region. The array layer includes gauge lines overlapping the respective hinges. At least part of each gauge line overlaps one of the inner peripheral region and the outer peripheral region alone.
