Nano Generator to generate free electricity in Future

In today’s world energy is a major requirement by all of us. In fact every portable device like laptops, radio and all requires electrical power and that comes with the help of batteries. But as Science is developing day by day, so in this advancement it has been seen that nano-wires which are not much expensive can produce a descent amount of electrical energy from mechanical energy. These can be done by running medical implants from pulsing blood vessels and our mobile phones can be charged using nanowires in the soles of shoes. 

According to Zhong Lin Wang, Professor of materials science at Georgia Tech who is one of the prominent researchers of the work says that a lot of mechanical energy of our body like can be converted into electrical energy. The amounts of electrical energies produced by different movement of bodies are listed below. However, only 17-30% of the total can be converted in to use.

It has been seen that a zinc oxide nanowire shows a very powerful piezoelectric effect. This is because the production of electricity is in response to mechanical pressure. In ordinary crystalline nanowires the positive and negative charges of Zinc and Oxygen ions respectively cancel out the charges of each other. Instead when the wires are chemically grown to stand on end on top of an electrode, it bend in response to any mechanical vibrations and as a result the ions are displaced and this results into mis-balance of charges. This misbalance in the charges among zinc and oxygen ions creates an electric field. Electricity can be produced putting up nanowires in the circuit. 

But yet the electricity produced by a single nanowire is very small. Professor Wand says that, “arrangement of several nanowires simultaneously produces a great output which is enough to run a small medical implant. Wang also reported that, technology to harvest power from multiple nanowires has already been developed by him. 

 

The making of these nanowires costs very less and it may be brought into practical life to use that nanowire generated electricity. According to Wang, “it’s made by putting polymer substrates at very low cost and their goal is to put those nanowires in the shoes of the people one day, so you can generate electricity when you're walking."
