Energy harvesting for self-powered wearable device applications

Abstract

The universal energy demand and pollution have prompted research scientists to explore other energy harvesting technologies that can generate energy from the natural resource environment, mainly due to the use of conventional energy sources. Energy harvester can be extracted and to convert into useful electric energy. The piezoelectric energy harvester is an excellent method of extracting mechanical energy due to its high electric and mechanical combination and piezoelectric harvester coefficient to compare electro-static, electro-magnetic, and triboelectric transitions. Therefore, the harvesting of piezoelectric energy is highly appreciated by the scientific community. Energy harvesters can be used to convert electrical energy into strong vibrations, which can be to store and used on a variety of ultra-low power electronic devices. With the advent of a various variety of wearable digital devices and fitness tracking devices, the piezoelectric generator suitable for portable and wearable electronic power source is one of the most interesting.
