Infrared Spectroscopy in Molecular Study of the Piezoelectric Effect in Pig's Shin Bone

Despite growing number of literature demonstrating the piezoelectric effect in bones at macro level there’sstill a lack of papers describing this effect at molecular level. In order to examine this effect more specifically,a study has been conducted to show the possibility of using infrared spectroscopy on samples contained in theelectricfield.
