A capsule for measuring motility of a target area and a method for making the capsule are provided. The capsule comprises a capsule enclosure and a plurality of identification markers to be placed inside of the capsule enclosure. Each identification marker has a weight of W, being comprised of a first element, which can be visible and imaged under X-ray, having a weight of W. Each identification marker comprises a second element, which cannot be imaged under X-ray, having a weight of W; and a third element, which is a number of cavities. When the first element is viewed under X-ray, at least two views of the first element is identical. The weight of each identification marker W=W+W; and when there is a weight change in the first element or in the second element, the shape, number and/or sizes of the cavities are adjusted and accommodated so that the weight of the identification marker is at a target value, which characterized by that each identification marker has a density between 1.0-1.7 g/cm.
