Pelvic or other types of implants are provided that can include tensioning feedback components or portions, such as color changing polymer materials, such as polyacetylene. The color changing polymer can be included with, coated on or otherwise provided with a portion of slings or implant devices to provide targeted feedback to the user or physician of the tension applied to a particular device. A first color can be used to indicate a first (initial) tension or compression stage, and a second color can be used to indicate tensioning of the device beyond a predefined threshold.
