Abstract: Provided is a strain sensor. The strain sensor according to embodiments of the inventive concept includes a flexible substrate, rigid patterns on the flexible substrate, the rigid patterns including a first pattern and a second pattern spaced apart from the first pattern in a first direction, a first electrode on the first pattern, a second electrode on the second pattern, the second electrode being spaced apart from the first electrode, and a piezoresistive layer connecting the first electrode and the second electrode. Here, each of the rigid patterns may have a stiffness greater than that of the flexible substrate.
