Abstract
The field of wireless sensors and portable electronics devices gained more attraction and growth over the years. Almost all the devices are powered using chemical batteries. Several energy sources are available in the environment in different parameters, which could be able to convert into an electrical parameter to power the portable devices and wireless sensors. This article reviews the harvesting of vibrational energy and converting it into electrical energy using piezoelectric materials. The sources of energy and conversion mechanism used to convert one type of energy into electrical energy were discussed. The different types of piezoelectric materials, various geometries of the substrate, resonant tuning methods of the harvester, placement of piezoelectric materials, and proof mass on the substrate were also reviewed.
