Abstract: An enhancer for simulating breast tissue includes a first layer of material and a second layer of material coupled to the first layer of material, where the second layer of material includes a wicking material. The enhancer also includes an third layer of material and a fourth layer of material both disposed generally between the first layer of material and the second layer of material. The third layer of material includes a plurality of monprene beads, and the fourth layer of material includes a plurality of open cell poly foam pieces. The enhancer further includes a fifth layer of material disposed at least partly between the third layer of material and the fourth layer of material, where the fifth layer of material is configured to inhibit mixing of the monprene beads of the third layer and the open cell poly foam pieces of the fourth layer.
