Abstract:
1. An apparatus comprising: an energy harvesting device configured to supply a current to an energy storage device, such that the energy harvesting device is capable of capturing energy from sources external to the energy harvesting device; a voltage multiplier directly connected in series to the energy harvesting device, the voltage multiplier configured to: receive an alternating current from the energy harvesting device, convert the alternating current to a direct current, and increase a voltage of the alternating current converted to the direct current; a voltage regulator directly connected in series to the voltage multiplier, the voltage regulator configured to adjust the direct current to a desired current for storage of the desired current in the energy storage device, such that the voltage regulator comprises a zener diode; and a Schottky diode, configured: to receive current from the voltage regulator, immediately following in sequence and directly connected to the zener diode, and immediately preceding and directly connected to the energy storage device.
