Abstract
A stretchable device includes a resin base member, strain gauges, and electrical wiring. The strain gauges include a longitudinal strain gauge and a lateral strain gauge. The electrical wiring includes an electrical wiring line for longitudinal strain and an electrical wiring line for lateral strain. The electrical wiring line for longitudinal strain and the electrical wiring line for lateral strain each include a first potential line, a second potential line, a coupling line, a first signal line, and a second signal line. The first signal line detects a third potential at a first coupling point where the second end of the corresponding strain gauge is coupled to the second potential line. The second signal line detects a fourth potential at a midpoint of the coupling line. The amount of change in resistance of each strain gauge is detected based on a difference between the third potential and the fourth potential.
