We report an electrospinning approach to producing P b T i O 3 polycrystalline nanofibers. The influence of the polymer concentration in the solution on the obtainable P b T i O 3 nanofiber morphology was investigated. Nanofibers were characterized by high‐resolution scanning electron microscopy ( HR ‐ SEM ) and Raman spectroscopy. After annealing at 500°C for 3 h, the continuous structure of nanofibers remained intact. Only tetragonal P b T i O 3 was identified by Raman spectroscopy. Piezoelectric behavior of P b T i O 3 nanofiber mats was demonstrated by making a nanomat‐based voltage generator with peak output voltage >1 V.
