Structure, dielectric and piezoelectric properties of donor doped PZT ceramics across the phase diagram

The effects of Zr/Ti ratio on the dielectric and piezoelectric properties of the sintered Pb(Zr_xTi_(1−x))_0.99Nb_0.01O₃ piezoelectric ceramics across the entire range of phase diagram of the PZT solid solution was studied systematically. The materials were prepared by the conventional mixed...

Direct strain energy harvesting in automobile tires using piezoelectric PZT–polymer composites

Direct piezoelectric strain energy harvesting can be used to power wireless autonomous sensors in environments where low frequency, high strains are present, such as in automobile tires during operation. However, these high strains place stringent demands on the materials with respect to mechanical failure or depolarization, especially at...
