Experimental Determination of Effect of Variable Resistance on Lead Zirconate Titanate (PZT-5A4E) under various Thermal and Frequency Conditions (original) (raw)

A specially designed apparatus and circuit working on the principle of inverse piezoelectricity due to the effect of polarization was used to find the relationship between resistance and peak to peak voltage of Lead Zirconate Titanate (PZT-5A4E)by shocking it at variable frequencies and at variable resistances under various thermal conditions within Curie temperature limit using equivalent circuit method. It was found that by increasing temperature, peak to peak voltage increases and similarly by increasing frequency, peak to peak voltage decreases and with the increase in resistance peak to peak voltage decreases.

Lead Zirconate Titanate: A Piezo electric material

Journal of chemical and pharmaceutical research, 2015

Lead Zirconate Titanate [Pb ZrxTi1-x]O3 ((0≤x≤1) - is an intermetallic inorganic piezoelectric material have been the subject of active research in recent years because of its remarkable applications in many field like microelectromechanical (MEMS) and nano-electromechanical (NEMS) devices. PZT is a metallic oxide based piezoelectric material developed by scientists at the Tokyo Institute of Technology around 1952. In comparison to the previously discovered metallic oxide based piezoelectric material Barium Titanate (BaTiO3), PZT materials exhibit greater sensitivity and have a higher operating temperature. PZT based materials are components of ultrasound transducers and ceramic capactitors. Ceramics also exhibit certain extremely useful magnetic and electronic properties that provide for a very wide range of possible applications.
