3. Definition materials whose physical properties can be changed in a controlled manner by factors like temperature, pH, pressure, electric/magnetic fields.

4. Types of smart materials I. Piezoelectric materials deformed, it gives off a small but measurable electrical discharge.(vice versa ) used as sensors in different environments Eg. airbag sensor, robots

5. Types of smart materials II. Electro-rheostatic and Magneto-rheostatic. fluids, which can experience a dramatic change in their viscosity. MR fluids: a viscosity change when exposed to a magnetic field ER fluids: a viscosity change when exposed to a electrical field use in car shocks, damping washing machine vibration…ext
