semi-interpenetrated PNIPAAm/PAAm networks, which could function as artificial
muscle instead of a robot powered by electricity. The resulting hydrogel was sensitive to temperature and acetone concentration, since PNIPAAm and PAAm are
respectively sensitive to these parameters. The hydrogel hand could lift or drop an
object controlling the rise or fall of temperature (Fig. 3.6).
Smart drug delivery systems (DDS) can be defined as those materials of controlled and sustained drug release upon the application of an external stimulus. As
shown in Fig. 3.7, this type of system could perceive a signal generated by injury,
