Lead-Free Piezoelectric Materials

Gadolinium-doped cerium oxide could be a promising alternative to certain piezoelectric materials. It is lead-free, which means that it could be employed in biocompatible medical applications. Further research will be conducted on this highly promising compound and similar materials. By manipulating atomic defects in a lead-free material that is normally not piezoelectric, it is possible to induce a large piezoelectric effect.
