ecting the level of battery in an electronic device, for example a cell phone, and is able to charge the device automatically as soon as the level of battery in the device falls lower than a specific threshold. The system of resonant induction charging will be utilized in our project which possesses the capability of charging several devices simultaneously unless they all bear the same resonant frequency.   The system would comprise of three key mechanisms: wireless power transfer, unit battery indicator, and the transducer/receiver unit.

The battery indicator would produce a warning sign when the level of battery to be charged in the handy device goes up to a particular threshold value. As soon as the battery drops below a particular brink, the battery indicator’s first LED will be powered off and, afterwards, the dropping edge will be detected by the edge detector. The signals from the edge detector will be held be the SR latch which, in turn, will turn on the switch. A transducer will be fed the warning signs from the switch which connects to the receive located in the charging dock.

The transducer, also called an ultrasound transducer, releases the ultrasound signals. The signal is fed into the rectifier once it is detected by the receiver in the charging dock, and is then, converted to a uniploar signal from the swine signal. The DC voltage will be obtained by the feeding and conversion of the unipolar signal into low pass filter. To lessen the undulation of the DC voltage, the application of the voltage regular is done, which results in the formulation of a flat DC voltage capable of turning on the switch.

Ultimately, the power supply unit is turned on in the dock and the AC wall outlet draws the power. Then, the 60 Hz AC current converts to a frequency which is higher enough to be appropriate for the power to transfer (for example, 13.56 MHz in the ISM band). The wireless power unit is then fed the up-converted AC current. A pair of resonant loop
