Wireless Power Transfer using Audio Signal and Magnetic Induction

Nowadays, portable electronic devices are extremely common. Almost all portable devices are battery-powered, which means they would all need to be recharged at some point-using the wired chargers currently in use. As mobile devices become more popular, charging their batteries has become a major issue. Wireless Power Transfer or Transmission (WPT) technology is at the cutting edge of electronic advancement. In This Paper, present a new era of power transfer without any wire. Wireless Power Transmission through Mutual Magnetic Induction is a new way of transferring power without the spider waves of wires. We are also trying to power up the circuit without giving it power from the power source. We are trying to power up the circuit from the surrounding audio signals. We will be receiving the audio signals by microphone from nearby sounds, the circuit will amplify the audio signals, and the circuit will convert the audio signals into energy, and the energy into power. After converting the energy, the action of mutual magnetic induction will take place. We will wind copper coils with appropriate turns to have a perfect induction. After winding the coils, if the devices are wireless charging capable, they will receive power by getting closer to the circuit. For those receiving devices that do not have wireless charging preinstalled, will be making a receiving circuit so that they can also receive power wirelessly. We will be also having software that will be connected with the device to maintain its functionality. For saving the time and for power-up implanted medical devices in the human body that are hard to recharge repeatedly, the device will be the best option. By making, this device in the industry the cost will become very low and everyone can have this wireless power-transmitting device for charge and power up multiple devices at a time.
