Nanogenerators

Rechargeable batteries Consumer electronic devices such as laptop computers and cell phones, portable systems, health monitoring, infrastructure, environmental monitoring, defense technologies and many other micro and nano systems require small power in the range of micro to milli Watts. For operating these portable electronics devices the current technology mainly relies on rechargeable batteries. But the traditional batteries have their inherent drawbacks and may not meet or be the only choice as power sources and hence the reason for new ultra light weight, high power battery developments. Nanogenerator A new idea is to have self powered nanotechnology, aiming at powering these devices using the energy harvested from the environment in which the systems are supposed to operate. The answer is nanogenerator. Nanogenerator is a technology that converts mechanical or thermal energy produced on small-scale into electricity. Nanogenerator can be broadly three types: piezoelectric, triboel
