ABSTRACT:
NANO…means one billionth of one and one third of micro, to be precise (10−9 meters). Nanotechnology is simply an emerging frontier and the future science paving the best way for most of cutting edge technologies. NEMS technology has been a realm in which machines operate at scales of billionth a meter. Recent innovations in nanotechnology revealed many potential applications in fields such as energy, medicine, electronics, computing and many more.The most advanced innovation in the field of nanotechnology is nanogenerators .These are futuristic and most advanced technologies which are quiet compact and harvest mechanical energy from the environment using an array of tiny nanowires. These nanogenerators find many applications in very small electronic devices; self powered micro devices and many more practical applications.
INTRODUCTION:
Nanoscale devices that harvest mechanical energy from the environment using an array of tiny nanowires are called nano generators. A nanowire is a nanostructure, with the diameter of the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length.
WHAT IS PEIZO ELECTRICITY?
The word piezoelectricity means electricity resulting from pressure. Piezoelectricity is the charge which accumulates in certain solid materials in response to applied mechanical strain. Piezoelectricity is the direct result of the piezoelectric effect, which is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials. The internal generation of electrical charge resulting from an applied mechanical force is called as piezoelectric effect piezoelectric effect is due to the occurrence of electric dipole moments in solids.
Self-powered nano/micro devices
One of the feasible applications of nanogenerator is an independent or a supplementary energy source to nano/micro devices consuming relatively low amount of energy in a condition where the kinetic energy is supplied continuously. One of example is the self-powered pH or UV sensor integrated VING with an output voltage of 20~40 mV onto the sensor.
Still, the converted electrical energy is relatively small for operating nano/micro devices; therefore the range of its application is still bounded as a supplementary energy source to the battery. The breakthrough is being sought by combining the nanogenerator with the other types of energy harvesting devices, such as solar cell or biochemical energy harvester this approach is expected to contribute to the development of the energy source suitable for the application where the independent operation is crucial, such as Smartdust.
CONCLUSION:
In future a day may come when nanogenerators power the entire globe. The nanogenerators would certainly bring up a new industrial revolution in the power generation .With the application of nanotechnology in every sphere of the life many compact designs can be expected which constitute for the technological development .With their size, precision and accuracy nanogenerators are definitely going to be an un-avoidable part of our future.
