                            Smart Materials
     • Materials with coupled properties in two (or 
        more) physical domains that are used to sense 
        or control behavior 
     • Physical domains?                      • Mechanical
           • Electrical                            -  Thermal
               -   Ferroelectrics             • Magnetic
               -   Piezoelectrics                  -  Shape Memory Alloys (SMA)
               -   Electrorheologic                -  Thermal expansion 
           • Magnetic                         • Multiferroic
               -   Ferromagnetic SMA               -  coupled ferroelectric and  
               -   Magnetostrictives                  magnetostrictive domains 
               -   Magnetorheologic           • Ionic gradient (”Nastic”)
           • Optiical                         • Pneumatic Artificial Muscle
