Bismuth Sodium Titanate Based Materials for Piezoelectric Actuators [PDF]

open access: yesMaterials, 2015
The ban of lead in many electronic products and the expectation that, sooner or later, this ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate-Titanate has motivated many research groups to look for lead-free substitutes. After a short overview on different classes of lead-free piezoelectric ceramics with large strain,
