Abstract
Various aspects of a self-chargeable portable electronic device with a power generating circuitry and a method to charge a rechargeable battery by the power generating circuitry are disclosed. The power generating circuitry includes an accelerometer that is configured to generate a sensing pulse based on activation of the accelerometer. The power generating circuitry also includes a plurality of capacitors and one or more circuits. The one or more circuits are configured to receive the sensing pulse from the accelerometer. The plurality of capacitors are charged based on the received sensing pulse. The one or more circuits are configured to control transfer of power from the charged plurality of capacitors to a battery.
