Characterization of Piezoelectric Response of PZT Nanofibers

This paper reports the characterization of piezoelectric response of the Lead Zirconate Titanate (PbZr₅₂Ti₄₈O₃) PZT nanofibers by three-point bending test using dynamic mechanical analyzer (DMA). PZT nanofibers were fabricated by sol-gel electrospinning process. The diameters of the fiber obtained were from 50 to 150 nm. The fiber consists of nanocrystal grains with average grain size of 10 nm. Titanium strip was used as substrate to collect the nanofibers for the three-point bending test to demonstrate the piezoresponse. The output voltage from the nanofibers under 0.5% strain was 0.17±0.005V, which was recorded by Labview. These results have shown that PZT nanofibers have great potential for nano sensor and actuator applications.
