Energy Harvesting Potential of Lead Free NBT-BZT Piezoelectric Ceramics
Akyurekli, Ayse Gul; Gurbuz, Mevlut; Gul, Mert; Gulec, Hakan; Dogan, Aydin (Ieee, 2014)In this study, Zr doped NBT-BZT (94Na(0.5)Bi(0.5)TiO(3)-6BaZr(x)T(1-x)O(3)) (x=0.1) powder was synthesis with solid-state method. The sintering process was carried out at between 1035 to 1180 degrees C in air for 2h. The ... -
A new design to improve bandwidth of piezoelectric energy harvester
Gulec, Hakan; Gurbuz, Mevlut; Toktas, Ayse Gul; Gul, Mert; Koc, Burhanettin; Dogan, Aydin (Springer, 2020)This study proposed a unique wideband energy harvester with a spiral metal plate design which has the potential to harvest vibrational energy over a broad range of ambient frequencies. In this design, metal shim with various ... -
Wide-Band Piezoelectric Resonance Frequency Energy Harvester
Gulec, Hakan; Akyurekli, Ayse Gul; Gul, Mert; Gurbuz, Mevlut; Koc, Burhanettin; Dogan, Aydin (Ieee, 2014)Some of the piezoelectric devices work more efficiently around the resonance frequencies. Piezoelectric structures have the highest displacement and charge generation closer to the resonance conditions. In this study, a ...
