Recent advances in power generation through piezoelectric nanogenerators

Piezoelectric nanogenerators are promising for the miniaturization of power packages and self-powering of nanosystems used in implantable bio-sensing, environmental monitoring, and personal electronics. This paper reviews the importance of nanogenerators as well as the recent advances in power generation through nanogenerators with the power generation mechanism. This paper discusses several research and design efforts that enhanced the power generation to commercialize the nanogenerators not only in nano-systems, but also to power microelectronic devices, such as drive a commercial liquid crystal display, light up the commercial light emitting diode and laser diode. This paper will discuss the future goals that must be achieved to find their way to everyday use.
