Magnetically active SMPs

Although magnetic activation of SMPINCs holds promise, other sources of heating, including photothermal, have been explored for SMPINCs. In 2013, Xiao et al. used lasers and gold nanorods and nanospheres to acmate SMP [ 129] (as shown in Fig. 11). 

Although the electronic properties of magnetic SMP systems have been explored, this has usually been seen as a secondary focus. However, in 2012 Fu et al. showed that Joule heating of a CNT nanocomposite in a polystyrene matrix was able to achieve a shape change while imparting electro-active properties to the SMP [131]. The electrical properties were shown to be strongly dependent on CNT concentration, testing frequency, and temperature.
