Abstract

Piezoelectric energy harvesting has attracted wide attention to fulfill day-byday increasing energy demand. Owing to its benefits, which include scalability, high power density, and simple architecture, piezoelectric ceramics have become the first choice of researchers over their counterparts such as electromagnetic and electrostatic energy harvesters. Despite extensive research and widespread use of lead-based piezoelectric ceramics, removing lead from these applications for environmental concerns is still difficult. Modern lead-free piezoelectric energy harvesting technology is reviewed in this chapter. Fundamental piezoelectric concepts and several piezoelectric material qualities are presented in a succinct theory part. A literature review on the advancement of lead-free piezoelectric ceramics, specifically KNN, BT, and BNT-based ceramics, since 2010 is presented. Applications for energy harvesting have also been described and assessed. Finally, based on their current developments, different challenges and future perspectives are also encompassed.
