Lead-free acoustic emission sensors [PDF]
Review of Scientific Instruments, 2007 Acoustic emission (AE) sensors have been fabricated using both soft- and hard-type lead-free (Na0.5K0.5)NbO3-based ceramics. The acoustic and electromechanical properties of the ceramics have been determined using the resonance technique. The lead-free AE sensors were calibrated using a laser source and compared to a commercial sensor. A lead zirconate

Lead-free multilayer piezoelectric transformer [PDF]
Review of Scientific Instruments, 2007 In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94(Bi1∕2Na1∕2)TiO3–0.06BaTiO3 ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3mm long, 8.3mm wide, and 2.3mm thick. It operates in the second thickness extensional vibration mode.
