An absorbent article for preventing leakage is provided, the article including an absorbent assembly having an absorbent assembly perimeter, and a leakage warning element disposed adjacent a portion of the perimeter, wherein the leakage warning element includes a dimension change member adapted to dimensionally change upon liquid contact to produce a transition in the absorbent article between an activated state and an un-activated state, thereby producing a physical sensation indicating a fullness level of the absorbent assembly. The absorbent article also provides an absorbent assembly having an absorbent assembly perimeter and a leakage warning element including a stored energy device and a dimension change member, the dimension change member disposed along a portion of the perimeter, wherein the dimension change member is adapted to break upon liquid contact to produce a transition in the leakage warning element from an un-activated state to an activated state.
