Abstract: A touch sensor includes a base layer, a first electrode unit, second electrode units, and a first strain gauge. The first electrode unit includes first touch electrodes arranged on the base layer along a first direction and electrically connected to each other along the first direction. The second electrode units are spaced apart from one another along the first direction. Each of the second electrode units includes second touch electrodes arranged on the base layer along a second direction intersecting the first direction and electrically connected to each other along the second direction. Each of the second touch electrodes includes a first opening. The first strain gauge includes first resistance lines electrically connected to each other along the first direction. Each of the first resistance lines is disposed in a respective first opening disposed in a first row among the first openings.
