Life in this world is changing consistently and there’s a great demand for new technology that would make the information available at each one’s comfort and at required place.. A new technique for turning sound into electricity that allows re-charging Phones using nothing but the power of the human voice. When we are in important conversation with any official on mobile, then if our battery gets flattened, our works get disturbed. But by using this technology called “VOICE USAGE TO CHARGE MOBILES” there is no possibility of flattening of the battery.
Sound pollution is a great disadvantage that we come across our daily life.. By using this technology we can convert this great disadvantage to our use.
This technology works on the principle of piezoelectric phenomenon.
(Conversion of mechanical energy into electrical energy)
What is Piezo?
Piezo is used to describe materials that accumulate a charge as a result of the piezoelectric effect. Piezo materials, including crystals and ceramics generate a voltage in response to an applied mechanical stress. In what is known as the inverse piezoelectric effect, these same materials will lengthen or shorten in response to an applied voltage.
The voltages, movements, and forces generated by piezo materials are small and usually require amplification. For example, a typical disc of piezolectric ceramic will increase or decrease in size by only a small fraction of a millimeter. In spite of this minor change of thickness, piezoelectric materials are used in many far-reaching applications.
Piezoelectric ceramics are a preferred material choice due to their ability to be tailored to meet the requirements of a specific purpose. Currently, PZT (lead zirconate titanate) materials are the most widely used piezo ceramics. They offer greater sensitivity and higher operating temperatures than other piezo ceramics.
The technology uses tiny strands of zinc oxide sandwiched between two electrodes. A sound absorbing pad is placed on the top of the sandwiched zinc oxide electrodes. Sound absorbing pad on top vibrates when sound waves generated, hit the sound absorbing pad. This results in the tiny zinc oxide wires to compress and release.
The compressions and rare fractions are due to the sensitivity of the Zno. A nanogenerator is placed between the sandwiched zinc oxide electrodes. The compressions and rarefractions are given to the nanogenerator. The nanogenerator converts the given mechanical energy into electrical energy. The generated electrical energy is used to charge the battery.
Nanogenerator is a technology that converts mechanical/thermal energy as produced by small-scale physical change into electricity. Nanogenerator has three typical approaches: piezoelectric, triboelectric, and pyroelectric nanogenerators. Both the piezoelectric and triboelectric nanogenerators can convert the mechanical energy into electricity. However, the pyroelectric nanogenertors can be used to havest thermal energy from a time-dependent temperature fluctuation
• We are vexed up with the normally Used lithium ion, cadmium batteries. Voice usage to charge mobile phones creates a new era with cleanly environment along with saving energy.
