Describe the characteristic(s) of these


                             materials: shape memory alloys,



                             piezoelectric ceramics, magnetostrictive



                             materials, and electrorheological/



                             magnetorheological fluids.




                                      Piezoelectric ceramics expand and


                                      contract in response to an applied electric


                                      field (or voltage); conversely, they


                                      generate an electric field when their



                                      dimensions are altered. The piezoelectric


                                      materials are high sensitivity, resonance


                                      frequency, stability, etc.
