Abstract

In today's era of low-power wireless applications, devices are mainly dependent on battery for source of energy. Batteries of these devices could be replaced by “lead zirconate titanate (PZT)-based power harvesting unit,” which can harvest electrical energy by converting mechanical energy in the form of vibrations and movements, available on large scale in the nature. This requires modification of PZT to obtain properties suitable for power harvesting so as to generate optimum electrical output. Significant work is carried out towards device development for power harvesting by using commercially available piezoceramic materials, but very small quantum of research work is carried out towards tailoring of PZT-based piezoceramics for power harvesting applications.
