  1. Flexible magnetostrictive devices for wireless power harvesting and transport Ben Siegfried McAlpine Group Department of Mechanical and Aerospace Engineering Princeton University

  2. What is Energy Harvesting? From the Natural World From the Human Body Scavenging power for small scale energy systems T. Starner, IBM Syst. J., 1996, 35, 618–629. http://www.superstock.co.uk/stock-photos-images/1555R-308348

  3. Using piezoelectric materials • Piezomagnetism: mechanical strain --> voltage • BUT: fragile; necessitates fabricating gold electrodes Y. Qi, J. Kim, T. D. Nguyen, B. Lisko, P. K. Purohit, M. C.
