Mitsubishi have discovered Diaplex® membrane as Shape-Memory Polymer. Diaplex® is affected by heat or moisture, so this provide users thermal comfortability (Figure 11).
Fig. 11. Diaplex® adaptive membrane (Parys M. V., 2001).
The other example of Shape-Memory polymer is Dermizax®. This textile polymer is affected by microclimates.
As the microclimate rises, the openings between the polymer molecules in the membrane expand, thereby increasing
the fabric moisture permeability. As the temperature drops the pores close, thereby trapping heat (Figure 12).

Figure 13 shows shape memory foams. Bayer developed a pillow, this pillow can adjust its shape to the contour
of the neck and shoulder according to body temperature. SMP foams can be used as memory mattresses to provide
body comfort. SMP foams can be used to prepare insoles, which can effectively improve shoe fitting (Gefen A,
Megido-Ravid M, Itzchak Y. & Arcan M., 2002).
