A sensor device includes a substrate having stretchability, a first wire and a second wire embedded in the substrate and spaced apart from each other in a first direction, and a deformation controller positioned on a first surface of the substrate. The first wire may overlap the second wire in the first direction to form a capacitor, and the deformation controller may overlap the capacitor in the first direction. A Young's modulus of the deformation controller may be greater than a Young's modulus of the substrate, and the substrate may have a gap between the first wire and the second wire.
