Voice usage mobile charging
Researchers have developed a technology that can convert sound energy from the environment into electrical power. It uses a piezoelectric material such as zinc oxide that produces a voltage when subjected to mechanical stress from sound waves. The document describes how the technology works by using sound absorbing pads, zinc oxide electrodes, and a nano-generator to convert mechanical energy from sound into electrical energy that can be used to charge batteries. It has potential applications in powering devices in remote locations or insulating structures to capture wasted noise energy.

Sound that always exists in our everyday life and environments has been overlooked as a source. This motivated us to realize power generation by turning sound energy from speech , music into electrical power. Sound pollution is a great disadvantage that we come across our daily life. But using this technology we can convert this great disadvantage to our use

- 9. Piezo used todescribe the materials that accumulate a charge as a result of piezoelectric effect. Piezo material , including crystals and ceramics generate a voltage in response to an applied mechanical force. In reverse piezoelectric effect, these same material will lengthen or shorten in response to an applied voltage. The voltage at force generated by piezo material are small and usually required amplification.
