The ambient vibrations can be of great promise for harvesting energy initially at small scale to use for micro and nano scale devices. Such vibrations converted to electrical energy by piezoelectric transducer due to their major significance. Various research journals have introduced the phenomenon of energy optimization to increase the generated power and used directly for application like sensors or storage devices. The energy can be available in various forms like vibration, light, temperature; gradient energy harvester does not require an external energy source and compatible with MEMS technology. Piezoelectric material shows the piezoelectric effect which says that a change in electrical charge will be there if the material is strained.
