 Title: Structural Magnetostrictive Alloys: From Flexible Sensors to Energy
  Harvesters and Magnetically Controlled Auxetics\n\nAbstract: Novel sensor
 s and energy harvesting transducers take advantage of the significantly ex
 panded design space made possible by recent advances in structural magneto
 strictive alloys. These alloys can be machined and welded\, have high frac
 ture toughness\, and can actuate\, sense\, and carry load while subjected 
 to tension\, compression\, and bending. The talk includes an introduction 
 to magnetostrictive materials and transduction\, and a discussion on the u
 se of low-cost rolling and annealing methods in lieu of more costly crysta
 l growth methods for making bulk iron-gallium (Galfenol) and iron-aluminum
  (Alfenol) alloys. The process of using magnetostrictive materials to conv
 ert mechanical energy into magnetic energy and then into electrical energy
  is explained and demonstrated using sensors and energy harvesting devices
  as examples. Examples of magnetostrictive devices include prototypes rang
 ing in size from nanowire-based pressure sensors to huge structures floati
 ng in the ocean that convert wave energy into electrical power for “comm
 unity-scale” energy needs. The recent discovery of a particularly unique
  attribute of these alloys\, their auxetic behavior\, will also be discuss
 ed. In both Galfenol and Alfenol\, both strain and magnetic fields can pro
 duce simultaneous increases in lateral and longitudinal dimensions\, with 
 measured values of the resulting Poisson ratio being not only negative\, b
 ut as low as -2.0 in some cases. Mechanical\, aerospace and civil engineer
 s should find the discussion on the use of magnetic fields to control auxe
 tic behavior quite interesting\n\nSpeaker(s): ALISON B. FLATAU\, \n\nYokoh
